COMMENTS

Related to hyperperfect numbers of a certain form.

Contribution from Daniel Minoli (daniel.minoli(AT)ses.com), Aug 27 2009: (Start)

Minoli defined the sequences and concepts that follow in the 1980 IEEE paper below:

- For t=2 to infinity, the sequence m(n,t) = n exp(t) - (n-1) is called a Mersenne Sequence Rooted on n

- If n is prime, this sequence is called a Legitimate Mersenne Sequence

- Any j belonging to the sequence m(n,t) is called a Generalized Mersenne Number (n-GMN)

- If j belonging to the sequence m(n,t) is prime, it is then called a n-Generalized Mersenne Prime (n-GMP).

Note: m(n,t) = n*m(n,t-1) + n exp(2) - 2*n+1.

These numbers play a role in the context of hyperperfect numbers.
