[QUOTE=LordJulius;627100]Why skip TF 2^79 to 2^80 ?[/QUOTE]He probably did it, but since it now shows up as a [URL="https://www.mersenne.ca/tfgaps.php"]TF gap[/URL] I redid it:

[QUOTE=Miszka;627135]I found 4 factors[/QUOTE]Nice! The smallest one would've been found in a few weeks by TJAOI, but you got there first.
Outside GIMPS range, but I recently found 3 factors for M[ca]4267897171[/ca] within 0.85 bits of each other: 73.915bit M4267897171 has a factor: 17807676876562259133311 74.723bit M4267897171 has a factor: 31174335411508659346271 74.765bit M4267897171 has a factor: 32092274269846547707271 
Magellan3s has again created a TF gap, twice, at M333332983. I think he needs to be more careful about something though I can't say what his specific issues are.
