This has been my lucky weekend (just yesterday, I found a T5K prime for CRUS):
26*3^1435875+1 may be prime, but N divides 3^((N1)/3))1, restarting with a=5 Time : 1308.400 sec. 26*3^1435875+1 is prime! (685088 decimal digits) Time : 1299.598 sec.

Congratulations carpetpool. It's good to see that at least some of the Top 5k contributors are nice people.
Well done!
