anti-perfect numbers
A number  $n$  is said to be anti-perfect if it is equal to the sum of the reverses of its proper divisors.

For example, 244 is anti-perfect since its proper divisors are 1, 2, 4, 61, 122 and the sum of their reversal is 1 + 2 + 4 + 16 + 221 = 244.

The known anti-perfect numbers are 6, 244, 285, 133857, 141635817
