Sometimes groups with torsion can have finite-dimensional $\underline{E}G$. ams.org/mathscinet-getitem?mr=1292018 | |

Mar 29, 2017 at 15:57 | comment | added | Mark Grant | The answer is no, because the presence of torsion forces $\Gamma$ to have infinite cohomological dimension. See e.g. Ken Brown's "Cohomology of groups", Chapter VIII.2. | |
