Abstract
The multiplicative structure of an odd perfect number , if any, is , where is prime, and . An additive structure of , established by Touchard, is that " OR ". A first extension of Touchard's result is that the proposition " OR " holds for (the extension is due to the fact that the second congruence contains also ). We further extend the proof to , prime, with the restriction that the congruence modulo does not include . Besides, we note that the first extension of Touchard's result holds also with an exclusive disjunction, so that is a sufficient condition because .
