I had neglected to consider that all the candidates I had been testing had been presieved to at least 1G, which would have completely eliminated any composite numbers from the sieve file. No wonder they were all prime.

 2010-05-20, 12:18 #60 gd_barnes     May 2007 Kansas; USA 23×1,319 Posts Although I see a couple of others already posted in this thread, this is the first 6-peat that I've noticed: 58*581^12745-1 is composite: RES64: [EAE6E65DBBBBBB87] (33.0549s+0.0014s) ...and the "8" following the 6 B's "almost" looks like a B. I thought I might have the first 7-peat posted here for a second. The 6 B's combined with the 3 E's and 2 6's mean that there are only 8 unique digits in this one.

If we ever have a residual with "ABCDEFG" in it, I'll be quite surprised.

Thanks for the cool info. Dave. One note: These 2 appear inconsistent:

Can you check that? Also, if it exists, I wouldn't mind seeing the residual with seven consecutive 0's in it.

Thanks,
Gary

It would appear that there is indeed one:
