... A k-superperfect number n is an integer such that σ k (n) = 2n, where σ k (x) is the iterated sum of divisors function. For example, 16 is 2-superperfect since its divisors add up to 31, and in turn the divisors of 31 add up to 32, which is twice 16. At first Suryanarayana only considered 2-superper ...

... It is not particularly difficult, it is not hard to guess a formula for magic number, and proving that this number has the desired “magic” properties is not that hard either. #1 A magic matrix. Consider the n × n matrix obtained by filling the rows of this matrix with the numbers 1, 2, . . . , n2 , ...
