<font color="#0000ed"><i>SUMMARY:</i></font><br>
<br>
<font color="#0000ed"><i>The class GF2XVec implements vectors of fixed-length GF2X's.&nbsp;&nbsp;You can</i></font><br>
<font color="#0000ed"><i>allocate a vector of GF2X's of a specified length, where the maximum</i></font><br>
<font color="#0000ed"><i>size of each GF2X is also specified.&nbsp;&nbsp;These parameters can be specified</i></font><br>
<font color="#0000ed"><i>either with a constructor, or with SetSize.&nbsp;&nbsp;It is an error to</i></font><br>
<font color="#0000ed"><i>try to re-size a vector of non-xero , or store a GF2X that doesn't fit.&nbsp;&nbsp;</i></font><br>
<font color="#0000ed"><i>The space can be released with &quot;kill&quot;, and then you are free to call SetSize</i></font><br>
<font color="#0000ed"><i>again.&nbsp;&nbsp;If you want more flexible---but less efficient---vectors, use</i></font><br>
<font color="#0000ed"><i>vec_GF2X.</i></font><br>
