In mathematics, the aliquot sum s(n) of a positive integer n is the sum of all proper divisors of n. Perfect, deficient, and abundant numbers are equal to, greater than, and less than their aliquot sums respectively. The aliquot sequence is the sequence obtained by repeatedly applying the aliquot sum function s. The aliquot sum function is also referred to as the restricted divisor function.[1]
