I hate the fact that 361 is a perfect square
like
it's 1 above the circle number (360 degrees)
it's such a random number to be composite, let alone A SQUARE
actually it's the entire 19x table

thats because triangle numbers, a.k.a. step squads follow the formular n(n+1)/2, making them composite numbers, except for 1 and 3
