I am to construct a space $X$, whose fundamental group is $\Bbb(Z/2Z)\times(Z/3Z)$, and compute its homology. I know that $X$ is (or could be) a wedge sum of the projective plane $\Bbb RP^2$ and the dunce cap. I know how to commpute the homology of both, but have problems with computing the homology group of their wedge sum.

  • $\begingroup$ The homology of a wedge sum is a direct product of homologies: math.stackexchange.com/questions/1555224/… $\endgroup$ – freakish May 4 '17 at 23:23
