Indeed, congratulations! This is a very prime day for CRUS...new prime size and CK records, plus a long-overdue prime over on the PRPnet base 2 drive!

Thank you guys, and my belated congrats to Ian!

The competition is tough as ever; while "InProcess" for a mere few hours the R49 number already slid from entrance position 87 to ...88. Sheesh!

HOLY COW! A huge congrats!!

Not only our largest prime...BY FAR our largest prime!





Edit: Items of interest: Although not a record, this does make 4 consecutive bases proven for Sierp bases 11 thru 14. The following TIES a record: Only 2 total k's remaining for 7 consecutive bases Sierp 8 thru 14. Only bases 9 and 10 have one k each remaining. This is tied with the same bases on the Riesel side. There, only base 10 has 2 k's remaining; all of the other bases are proven.

WOW! That's a big one for sure. Congratulations!

It's always nice to see another base <32 fall...since the early days of the project, there has been very little "low hanging fruit" left in that range. As such, any proof of a base <32 is a major accomplishment.
