Mersenne: Suggestions for Prime95 v19

Hi all, Now before the new version of Prime95 is released I have some suggestions for new function which should not be too difficult to add: - A menu item that forces the program to write intermediate data to disk. It is useful, when the user wants to install a new program or play a game

Mersenne: GIMPS totals.

1999-09-02 Thread Rick Pali
I understand that the differences between the GIMPS and the Primenet standings are an artefact of how GIMPS was up and running before Primenet. Consequently, anyone that joined and finished numbers before Primenet was running will have different totals on each list. My question is whether this

Dear Spike, In keeping with the Three bears, the perfect numbers would be "just right." The proper terminology to apply to these numbers are abundant (M4825, A5010) and deficient (M0514, A5100) numbers. Odd primitive abundant numbers (M5486, A6038) are: 945, 1575, 2205, 3465, 4095,
