For a ring R with identity, define Unip R to be the group of upper-triangular n matrices over R all of whose diagonal entries are 1. For i s 1, 2, . . . , n y 1, let S i denote the matrix whose only nonzero off-diagonal entry is a 1 in the ith row and Ε½ . Ε½ . i q 1 st column. Then for any integer m
