However, we can ask more detailed questions about the possible finite quotients of 3manifold groups, e.g. for G and H_1,…,H_n finite groups, does there exist a 3manifold group with G as a quotient but no H_i as a quotient? We answer all such questions. To prove nonexistence, we prove new parity properties of the fundamental Location:
