We have some language problems here. Just to clarify:

12 has divisors 1, 2, 3, 4, 6, 12. Is 6 the result you mean, or is it 28?

The rough model is the one he proposed, not yours:

What will be?
I interprete this as follows:

The quality of a multiplier m is about S/(m^1/3), where we consider m < n^1/3 only.

S might be
a) the sum of divisors of m, or
b) the number of disivors of m.
My first question in this post aims to clarify which of the two options is the correct one.

nesio, do I get that right so far?

Last fiddled with by Till on 2019-04-07 at 18:19 Reason: make clear that only one option for S is correct
