Abstract. Let ¾(n) denote the sum of positive divisors of the natural
number n. A natural number is perfect if ¾(n) = 2n. This concept was
already generalized in form of superperfect numbers ¾2(n) = ¾(¾(n)) =
2n and hyperperfect numbers ¾(n) = k+1
k n + k-1

In this paper some new ways of generalizing perfect numbers are inves-
tigated, numerical results are presented and some conjectures are estab-
lished.
