Never mind...duh, my post above can be ignored. 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.

how about:
Code:
299*2^631372-1 is not prime.  LLR Res64: 14CA1BADA557CE3B  Time : 347.597 sec.

35224*39^22457+1 is composite: RES64: [BEBEB5C064CF8645] (31.1162s+0.0027s)

Mildly interesting repetition there.

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.

where f(x) is Count of NPLB residuals containing (expression):

f("%ABCDEF%") = 15.
f("%DEC0DE%") = 9.
f("%BADF00D%") = 3.
f("%CAFEBABE%") = 0.

supplementaries:

f("%B00B5%") = 309. (would have been funny if it was an even number )
f("%123456%") = 13. (unlucky for some)
f("%1234567%") = 1. (that was a surprise)
f("%ABCDEFG%") = 0. (Ah well. Can't win them all)
f("%000000%") = 14.
f("%0000000%") = 1. (cool)
f("%00000000%") = 0. (nope. not yet)

If "PRIME" (ASCII) = "50:52:49:4D:45" (Hex)
f("%5052494D45%") = 0. (Awww. Darn it)

f("%BEEF15BAD%") = 0. (sorry. none yet)

Count of 7-petes:

f("%0000000%") = 0.
f("%1111111%") = 0.
f("%2222222%") = 0.
f("%3333333%") = 3.
f("%4444444%") = 1.
f("%5555555%") = 1.
f("%6666666%") = 3.
f("%7777777%") = 0.
f("%8888888%") = 1.
f("%9999999%") = 1.
f("%AAAAAAA%") = 0.
f("%BBBBBBB%") = 1.
f("%CCCCCCC%") = 0.
f("%DDDDDDD%") = 1.
f("%EEEEEEE%") = 0.
f("%FFFFFFF%") = 2.

No 8-petes found at this time.

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:
