For a number n, their sum is equal to 2n+1.

It states, "A quasiperfect number is a natural number n for which the sum of all its divisors is equal to 2n + 1. Equivalently, n is the sum of its non-trivial divisors (that is, its divisors excluding 1 and 'n')." But I am looking for a number for which the sum of most of its divisors is itself.
