Suppose k is a finite field, and n, m >= 4 multiples of the field characteristic. Then the A(infinity)-structure of the group cohomology algebras H* (C(n), k) and H* (C(m), k) are well known. We give results characterizing an A(infinity)-structure on H* (C(n) x C(m), k) including limits on non-vanishing low-arity operations and an infinite family of non-vanishing higher operations.
