Let b(m)(n) denote the number of partitions of n into powers of m. Define s
igma (r) = epsilon (2)m(2) + epsilon (3)m(3) + ... + epsilon (r)m(r), where
epsilon (i) = 0 or 1 for each i. Moreover. let c(r) = 1 if m is odd, and c
(r) = 2(r-1) if m is even. The main goal of this paper is to prove the cong
ruence b(m)(m(r+1)n-sigma (r)-m) drop 0 (mod m(r)/c(r)). For sigma (r) = 0.
the existence of such a congruence was conjectured by R. F. Churchhouse so
me 30 years ago. and its truth was proved by O. J. Rodseth. G. E. Andrews.
