Veit, Thanks. I didn't know anything about complex Hadamard matrices. One thing that I find quite interesting is the relationship between them and tiling of finite abelian groups. I have a recent paper about such a problem. Now I'm wondering about the relationship between that problem (whether or no a subset tiles the group Z_2^n) and the existence of complex Hadamard matrices.
