You are right... I thought about the multiples of 945... and it's

absurd...

look at the connection between abundant and perfect numbers when I

use the sigma function and the odd perfect number idea will disappear

...

sigma(abundant#) = 2*sigma(perfect#) + assoc. Mp + 1

sigma(4n) = 2*sigma(2n) + associated Mp + 1

sigma(2n) = 2*sigma(n) + associated Mp + 1

sigma(n) = 2*sigma(n/2) + associated Mp + 1

even if the form of an odd abundant# is not known... the odd perfect

number before it is...

typically when someone would investigates the abundant# linked to the

well known list of perfect numbers, they would see the first

equation... and then believe the last one and notice that an odd

perfect number was not possible... the odd perfect# couldn't be a

whole number. Look at the it's form. Also, the associated Mp is

derived by dividing out 2's from the perfect# until the prime is left

over... kinda like a modulo function or a new 'multilo' function.

the sigma function is tricky. I'm convinced implicitly. Bill
