comment Intuitively what is it if making a modification of a torus?
As far as I can tell, your modification is not an equivalence relation.

comment Derived functors and coboundary operator
@ZhenLin I'm not exactly sure what your point is, but as far as I understand, you can calculate group cohomology either from an injective resolution (which is difficult to find) or from a projective resolution with the Hom functor applied to the whole resolution.
