[QUOTE=mklasson;168788]Speaking of 128370, I notice it's one of the missing files on your 100k-200k page, Frank. Is the previous work for that seq coming or should I let an idle computer redo it a couple of nights?[/QUOTE]It depends on your preference. I'm feeding them up as I get them.

Thinking of the high powers of 3 again, I have found a 3^11 amongst the depths of 130396, shortly after the downdriver run ended. At 94 digits, is it a record?

Congratulations to Markus Tervooren aka Syd: the highest downdriver run became the longest at 100 digits and 535 lines!

:party::party::wblipp::bow wave::bow wave::wblipp::party::party:

A second downdriver run plunged it down to 26 digits. Side-sequence check passed. Now with 2^3*3, size 93, line 3923.

Hope I haven't missed anything!
