<p>Inputs a regular CW-complex <span class="SimpleMath">\(Y\)</span> and, optionally, the number of some 0-cell. It returns the fundamental group of <span class="SimpleMath">\(Y\)</span> based at the 0-cell <span class="SimpleMath">\(n\)</span>. The group is returned as a finitely presented group. If <span class="SimpleMath">\(n\)</span> is not specified then it is set <span class="SimpleMath">\(n=1\)</span>.

If <span class="SimpleMath">\(Y\)</span> does not initially have a discrete vector field then one is constructed.</p>
