[QUOTE=paulunderwood;606326]@ryanp and @Andreas. Please make a The Prime Pages database entry for your numbers.

I don't see Andreas' [C]ecpp[/C] software listed there. I attempted to create a new proof code using the existing FastECPP, but am not sure how to upload the prime + cert (just attempting to submit "(2^78737-1)/1590296767505866614563328548192658003295567890593" fails as it's too small).

On [url]https://primes.utm.edu/primes/status.php[/url] I see Serge uses "CM" and an "x" code. UTM does not accept certs.

To be more explicit: create an x prover code attributing you and CM. When you submit the number append it with: Mersenne cofactor, ECPP

Reserving [URL="http://factordb.com/index.php?id=1100000000017751314"]W117239[/URL].

I'd also like to take the next 3 Mersenne PRP cofactors [URL="https://www.mersenne.ca/prp.php?min=50000&max=120000"]here[/URL]: M86137, [STRIKE]M86371,[/STRIKE] and M87691.

Please don't take M86137 -- I have nearing the end of a Primo run of it.

Oops, OK. Anyone working on the other two?

Nope. They're yours.

It looks as though Prof. Chris Caldwell has now created an [URL="https://primes.utm.edu/bios/page.php?id=5485"]"E" prover code[/URL], which should be selectable to create a code in order to submit CM (FastECPP) proven numbers.

Reservation: I will do a few more primU(), primV(), primeA() and primB()'s.

For those who don't know what these are, you are not missing anything.

[QUOTE=paulunderwood;606277]Nearly finished:

M86137 cofactor prp25896

Dropping:

M86371 cofactor prp25984
M87691 cofactor prp26371
E(11848)/(5*1582043) prp40792

Reserving:

R86453[/QUOTE]

I am dropping R86453. It took my machine ~12 hours to reach "Step [0]". If a step gets stuck then the time involved to run say one core to get a different proof path is infeasible. Basically the job is way too big without some very big iron.

Reserving E(11848)/(5*1582043) prp40792 again. I expect this number to take a couple of months.

[QUOTE=sweety439;606293]
Suggest you to prove (18^25667-1)/17 = R25667(18), this prime is also a generalized repunit, and is much smaller than R49081, this prime is interesting (much more interesting than R86453, you think R86453 is interesting is only because we use the number 10 as the base (radix) of our positional numeral system) is because this prime is the smallest generalized repunit prime in base 18 apart from 19 = R2(18), see [URL="https://oeis.org/A128164"]https://oeis.org/A128164[/URL][/QUOTE]

I am reserving this number, (18^25667-1)/17.

My run of the Euler Irregular "got stuck" on Step [60] and I am manually backtracking from Step [58].
