© 2019 Korean Mathematical Society. Let TaDb(n) and TaDb(n) denote respectively the number of representations of a positive integer n by a(x2 - x)/2 + b(4y2 - 3y) and a(x2 - x)/2 + b(4y2 - y). Similarly, let SaDb(n) and SaD’b(n) denote respectively the number of representations of n by ax2 + b(4y2 - 3y) and ax2 + b(4y2 - y). In this paper, we prove 162 formulas for these functions.
