Recently Richard Stanley formulated a new partition fuction t(n). This function counts the number of partitions pi for which the number of odd parts of pi is congruent to the number of odd parts in the conjugate partition pi' modulo 4. G.E. Andrews has recently proven a nice generating functin for t(n) in terms of the generating function for p(n), the usual partition function. He also showed that the mod 5 Ramanujan congruence for p(n) also holds for t(n). In light of these results, it is natural to ask the following questions: What is the size of t(n)? Are there other congruences satisfied by both t(n) and p(n)? We will address both of these questions.
