The first two should be "prime", according to Norman. Maybe the certificates are not easily available.

You must know, double the number of digits you will test with primo, so the runningtime will be 16 times longer (or more). jump from 31000 to 40000 digit , about (40000/31000)^4 = 3. Example: You need 6 months to certify a 31000 number, than you need 12 months to fall down from 40000 to 31000 digits in Phase 1 (Primo) (estimated) 137h for a 27000 digit numer is UNBELIEVABLE fast ! 10 years ago,the old primo version 3.0.9 for windows and on a singlecore needed for 10000 digits (~limit) more than 10000h on a 3 GHz Phenom...40.000 digit ~ (double the digits was 22 times longer) you need 5 million hours or 600 years.

Sure! All the certificates are uploaded to factorDB, and my name should be listed as the certifier for them.
