Sure, mrh, I'd be delighted! I can't promise anything, esp. since it's been so well researched already, but my little computer will do her best and I daresay we'll both learn a lot in doing it. :) I'll try to get it going by Monday, after 123000169 wraps up.

You know, if I squint, 5891453 does end in 23: 1000000 x [1,1,2,3,3,1,1,23]. OMG, it's like a cousin to 123000023! :D

Warm hellos, one and all,

I was only half serious about 5891453, I threw a lot at it already and couldn't factor it. I do appreciate the beauty you see in the nice looking numbers!

I noticed, however, that there are 14 unverified LL and PrPs in the range 123xxxxxx, such as 123000023 („reliable“) and 123000169 („unverified“). I feel the urge to verify them, as a nice gesture to the people who made the effort to test them the first time.

So my question is: Is it better for the project to do *new* PrPs, rather than finishing up the once-verified? Or does it not make really any difference?
If still doing P-1, hopefully you're using v30.8 prime95 / mprime or later, and a considerable amount of ram allowed for stage 2 day and night.
There's a thread for doing remedial P-1 on double check candidates with unusually low-bounds prior P-1 ahead of the double-check wavefront.

Yes, palindrome exponents and especially two-digit-value palindromes can be pleasing. (The more so, the fewer changes between digit values scanning left to right there are, in my opinion.)

That mrh would know mrh's own gender seems a relatively safe assumption for mrh to make. Either by self inspection, or resort to expert opinion or DNA test in a rare ambiguous-physiology case, or whatever. (That's some mighty subtle humor there, Uncwilly!)

No apology necessary; the 2020-03-05 result was only a few days after the beginning of the thread describing the possibility of proofs, and months before Gpuowl (mid June 2020) and subsequently prime95/mprime (July 2020) became prp-proof-generation capable, with upload-to-server and cert-worktype following shortly after.

So subtle that some missed it.
