This makes sense algebraically: the braid group image associated with the Drinfeld center of a (generalized) Dihedral group is an integer specialization of the Burau representation, reduced modulo some $m$. The link invariant associated with this (modular) Hopf algebra is some version of counting homomorphisms. So maybe the statement you make can be generalized to semidirect products of cyclic groups? I think I read somewhere that the Alexander polynomial can be used to compute the homology of Seifert surfaces... | |
