observation ??
it appears that on average
with a integer > 1 and p an odd prime :
a^p + 1 has less divisors than a^p - 1.
is that true ? why ?
yes i know about fermat's little and (x^n - 1)/(x - 1) ( see another recent post by me ) , but still.
just because one can give some divisors in closed form for a^p - 1 doesnt seem sufficient to explain this weird observation ...
