Women's Relaxed T-Shirt - Purrfect Numbers, Imperfect Us?

Design Backstory

Not Ed Sheeran’s purring out his Perfect lovesong but official eternal perfect numbers. These are numbers equal to the sum of their proper divisors, excluding themselves (eg 6 = 1+2+3, 28 = 1+2+4+7+14). Euclid found a general rule to find a perfect number for primes. If an integer k, if 2^k-1 is a prime then it generates a perfect number using the formula 2^(k-1) x (2^k -1). Another associated design excludes the purrfect feline here.
