| Aug 18, 2022 at 15:48 | comment | added | M.Ramana | @Tyrone Thanks very much for the comment. You mean we use the fact that if $\mathcal{P}$ is a finite presentation of some group $G$, then there is a finite 2-dimensional CW-complex $K(\mathcal{P})$ with a single vertex in which the 1-cells correspond to the generators of $\mathcal{P}$ and the attaching maps of the 2-cells are given by the relations of $P$. Is that right? | |
