I am familiar with a "perfect Pythagorean Triple"
Is that what you want?
if so, then the 3 numbers should form the sides of a right-angled triangle.

The simplest such numbers are 3,4,5 since
3^2 + 4^2 = 5^2

another, 5,12,13 -- 25+144 = 169

yours does not work, since
13^2 + 15^2 is not equal to 18^2
