 [$\to$ \ref{Five}]

 In this section we present examples for all the various types of text that are
possible in \textsf{GAPDoc}: 
\begin{itemize}
\item  \emph{This} is \emph{emphasized}.
\item  \emph{Keywords} are typeset like \texttt{this} and \texttt{that}. 
\item  \emph{Arguments} of functions have an element. They look like this: \mbox{\texttt{\mdseries\slshape x}} and \mbox{\texttt{\mdseries\slshape y}}.
\item  \emph{Code} can be written with the Code element: \texttt{if x = y then Print("Equal"); fi;} or \texttt{while true do Print("Hello"); od;}.
\item  \emph{Filenames} have their own element: \texttt{/usr/local/ca/gap4r2} or \texttt{pkg/xgap/doc}.
\item  \emph{Buttons}, \emph{menus}, \emph{menu entries}, and such things are also supported: \textsc{OK} or \textsc{Cancel}.
\item  \emph{Packages} are typeset like this: \textsf{Small Groups Library} 
\item  \emph{Quoted} text: ``This is a text in quotes.'' 
\end{itemize}
 \emph{Paragraphs} are separated by the empty \texttt{Par} or \texttt{P} element. 

\emph{Alternatives} for different output formats: This is {\LaTeX} output.  

 \label{SixBack} There are also three elements to typeset ``verbatim\texttt{\symbol{45}}like'' text. ($\to$ \ref{Six})

 The first is a \emph{Listing}: 
\begin{Verbatim}[commandchars=!@|,fontsize=\small,frame=single,label=GAP code]
  Sieve := function(n)
    # Returns the primes less than n
    local l,p,i;
    l := [1..n]; Unbind(l[1]);
    p := 2;
    while p^2 <= n do
        if IsBound(l[p]) then
            i := 2 * p;
            while i <= n do Unbind(l[i]); i := i + p; od;
        fi;
        p := p + 1;
    od;
    return Compacted(l);
  end;
\end{Verbatim}
 Here is a \emph{Log} of a \textsf{GAP} session using this function: 
\begin{Verbatim}[commandchars=!@|,fontsize=\small,frame=single,label=Example]
  !gapprompt@gap>| !gapinput@Sieve(100);|
  [ 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61,
    67, 71, 73, 79, 83, 89, 97 ]
  !gapprompt@gap>| !gapinput@Length(last);|
  25
\end{Verbatim}
 Here is a \textsf{GAP} \emph{Example} session that is automatically tested: 
\begin{Verbatim}[commandchars=!@|,fontsize=\small,frame=single,label=Example]
  !gapprompt@gap>| !gapinput@s := Size(CharacterTable("M"));|
  808017424794512875886459904961710757005754368000000000
  !gapprompt@gap>| !gapinput@s < 10^53;                     |
  false
  !gapprompt@gap>| !gapinput@s < 10^54;|
  true
\end{Verbatim}
 }

 
\section{\textcolor{Chapter }{Formulae}}\logpage{[ 2, 2, 0 ]}
\hyperdef{L}{X7AA5BF0279938BE0}{}
{
 \label{SevenBack} [$\to$ \ref{Seven}]

 There are three types of formulae. 

 The first is the \emph{normal math mode} of {\LaTeX}: $b_i \cdot b_j = \sum_{k=1}^d h_{ijk} b_k$. Then there are \emph{displayed formulae}: 
\[ \Longrightarrow \quad \left(\sum_{i=1}^d x_i b_i \right) \cdot
\left(\sum_{j=1}^d y_j b_j \right) = \sum_{k=1}^d \left( \sum_{i,j} x_i y_j
h_{ijk} \right) b_k \]
 If possible, use the \texttt{Alt} element to specify a better readable text version of such a formula as in the
following example:

 
\[ \Longrightarrow \quad \left(\sum_{i=1}^d x_i b_i \right) \cdot
\left(\sum_{j=1}^d y_j b_j \right) = \sum_{k=1}^d \left( \sum_{i,j} x_i y_j
h_{ijk} \right) b_k \]
  For small formulae without ``difficult'' parts use the \texttt{M} element: $b_i$, $x^2$, $x^2 + 2x + 1 = (x + 1)^2$. Note that here whitespace matters for text (or HTML) output.

 Here are two formulae containing less than characters which are special
characters for XML: $a < b < c < d$ and $e < f$. 

 Using the \texttt{Mode} attribute of a \texttt{Display} element formulae like 
\[a \longrightarrow a \bmod m\prime\]
 can also be displayed nicely in text and HTML output. }

 
\section{\textcolor{Chapter }{Crossreferencing}}\label{Cross}

\hyperdef{L}{X833C410D85CF96A4}{}
{
 \label{EightBack} [$\to$ \ref{Eight}]

 \label{there} In this section we demonstrate various references to parts of this document.
Here is a reference to this section: \ref{Cross}. Here is a reference to chapter \ref{First}, to appendix \ref{Appendix}, and to subsection \ref{Asub}. 

 We distinguish among others references to functions (see \texttt{f} (\ref{f})), to methods with tricky name (see \texttt{\texttt{\symbol{92}}\texttt{\symbol{94}}\texttt{\symbol{92}}\texttt{\symbol{123}}\texttt{\symbol{92}}\texttt{\symbol{125}}\texttt{\symbol{92}}[\texttt{\symbol{92}}]\texttt{\symbol{92}}{\textless}\texttt{\symbol{92}}\&} (\ref{bSlash^bSlash{bSlash}bSlash[bSlash]bSlash<bSlash&:for nothing})), to operations (see \texttt{MyOperation} (\ref{MyOperation})), to methods (see \texttt{MyOperation} (\ref{MyOperation:First}) or \texttt{MyOperation} (\ref{MyOperation:for bla})), to filters (see \texttt{IsBla} (\ref{IsBla})), to properties (see \texttt{IsBlubb} (\ref{IsBlubb})), to attributes (see \texttt{NumberBlobbs} (\ref{NumberBlobbs})), to variables (\texttt{AllBlibbs} (\ref{AllBlibbs})), to families (see \texttt{BlibbsFamily} (\ref{BlibbsFamily})), and to info classes (see \texttt{InfoBlibbs} (\ref{InfoBlibbs})). 

 There are also references to labels: see \ref{there}, to other books: see  (\textbf{GAPDoc: What is a DTD?}) or \texttt{IsSubgroup} (\textbf{Reference: IsSubgroup}) in the \textsf{GAP} reference manual. 

 References to sections come in two styles: \ref{First} or \hyperref[First]{`Sectioning Elements'}. 

 Another type of cross referencing is bibliography. Here is a citation: \cite[(5.22)]{CR1} is an interesting lemma. 

 There are also URLs:

 \href{https://www.math.rwth-aachen.de/} {\texttt{https://www.math.rwth\texttt{\symbol{45}}aachen.de/}}

 Email addresses have a special element: \href{mailto://Frank.Luebeck@Math.RWTH-Aachen.De} {\texttt{Frank.Luebeck@Math.RWTH\texttt{\symbol{45}}Aachen.De}} 

 and Homepages another one: \href{https://www.math.rwth-aachen.de/~Frank.Luebeck/} {\texttt{https://www.math.rwth\texttt{\symbol{45}}aachen.de/\texttt{\symbol{126}}Frank.Luebeck/}} 

 And here is a link to the \href{https://www.math.rwth-aachen.de/~Frank.Luebeck/gap/EDIM/index.html#ARCHS} {\textsf{EDIM} archives}. 

 One can generate index entries as follows (look up the words ``{\TeX}\texttt{\symbol{45}}UserGroup'', ``RWTH'', ``Aachen, Hauptbahnhof'', and ``\textsf{GAPDoc}, for \textsf{GAP} programmers''). \index{TeX-Usergroup@{\TeX}\texttt{\symbol{45}}UserGroup} \index{RWTH} \index{Aachen!Hauptbahnhof} \index{GAPDoc@\textsf{GAPDoc}!for \textsf{GAP} programmers} }

  There are three types of formulae. <P/>
  The first is the <E>normal math mode</E> of &LaTeX;: 
  
  <Math>b_i \cdot b_j = \sum_{k=1}^d h_{ijk} b_k</Math>. 
  
  Then there are <E>displayed formulae</E>:
  <Display>
     \Longrightarrow \quad \left(\sum_{i=1}^d x_i b_i \right) \cdot

  </Display>
  
  If possible,  use the <C>Alt</C> element  to specify a better  readable text
  version of such a formula as in the following example:<P/>
  
  <Alt Not="Text,HTML"><Display>
     \Longrightarrow \quad \left(\sum_{i=1}^d x_i b_i \right) \cdot
