摘要：
Let (p) over bar (n) denote the number of overpartitions of n. In this paper, we shall show that for n >= 0, (p) over bar (80n + r) equivalent to 0 (mod 5), where r = 8, 52, 68, and 72. In addition, we present a short alternative proof of the congruence (p) over bar (40n + 35) = 0 (mod 5), which is conjectured by Hirschhorn and Sellers.
