CONJUGATE NETS.221 10.Professor Dickson has found certain polynomial modular invariants and properties of such invariants for the case of a binary n-ic and a prime modulus P. In this paper Professor McAtee generalizes these invariants for the case of a binary quadratic and modulus a power of a prime, P\ Then these invariants are specialized for the case P = X = 2 and a fundamental system is exhibited modulo 4.
