Abstract
We consider the problem of finding equiangular lines in complex space, i. e., sets of unit vectors such that the modulus of the inner product between any two vectors is constant. We focus on the case of d 2 such vectors in a space of dimension d which corresponds to so-called SIC-POVMs. We discuss how symmetries can be used to simplify the problem and how the corresponding system of polynomial equations can be solved using techniques of modular computation.
