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.
