Is there a known example of a Calabi-Yau manifold (say, a Kähler compact manifold with $c_1$ torsion) with finite simple (non cyclic) fundamental group, for instance $\mathfrak{A}_5$? I am pretty sure such an example is not known in dimension 3 (see this paper1), but perhaps it is easier to find it in higher dimension (?).

  • $\begingroup$ @Jason Starr: Well, I didn't rule out holomorphic symplectic manifolds. But I agree that finding a IHS manifold with a free action of $\mathfrak{A}_5$, hence of dimension $2(60k-1)$, is extremely unlikely. I had in mind the odd-dimensional case. $\endgroup$
