This refers to a set of three integers x, y, and z that satisfy the equation x 2 + y 2 = z 2. When m and n are any two integers, the general form is x = m 2 - n 2 , y = 2mn, and z = m 2 + n 2. The set of m = 2, n = 1, that is, x = 3, y = 4, z = 5, has been known since ancient times. → Pythagoras / Pythagoras' Theorem
