[QUOTE=nordi;606366][M]M36919[/M] has a 180.968-bit (55-digit) factor: [URL=""]2997347544642661833497896836795494793702018162645139063[/URL] (P-1,B1=2000000000,B2=401927737170960)

That gets me to the top of the [URL=""]list of P-1 factors for Mersenne numbers[/URL]! And all thanks to the new version 30.8 of mprime.[/QUOTE]

Using the 3 now-known factors - a quite impressive collection - the cofactor is still composite [C11008], so this is no time to rest on your laurels. :)

All times are UTC. The time now is 01:50.
