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.

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)

Think of it like this:

(7+1) == (1 mod 7)
-and-
(0+1) == (1 mod 7)

therefore x represents the same integer 0<=x<=6 in both of the following:
(7+1)^m == (x mod 7)
-and-
(0+1)^m == (x mod...

Oh come on now, you can do better than that!

Nice ones Mike! Very interesting.

So, if we find the "BEEF15BAD" residue, how can we know that you'll hold up your end of the bargain? Unless you're already a vegetarian, that would be quite a...

I know you like automating stuff but in this case, manually renaming/copying/moving or whatever it is you're after for 35 files would only take 10-20 mins.

Oh, you guys are just NUTS!!

Karsten, I about fell over laughing at your last suggestion. Converting residuals to decimal and finding primes. Now THAT is funny!!

I'm quite impressed by Max's...
