A primary pseudoperfect number is a type of integer closely related to the concepts of number theory, particularly with respect to the properties of its divisors. A positive integer \( n \) is called a primary pseudoperfect number if it can be expressed as the sum of a subset of its proper divisors (the divisors excluding itself) plus one.
