Simple functions were obtained for the rows of odd powers in the modular ring Z4, wherein integer N is represented by N = 4ri + i, i = 0, 1, 2, 3. These row functions are based on the row functions for squares. When 3 ∤ N , the row of N2 = 3n(3n ±1) , or when 3|N, the row of N2 = 2 + 18(½n(n+1)), n = 0, 1, 2, 3…
