cataloguing primes k*42n+1 for k = 1 ~ 15000, n = 1 ~ until i get bored. gotta catch 'em all, as they say.

current progress: n ~ 700

if someone's already done this, pls let me know.

attachments are n = 300 ~ 700 (1 ~ 300 too large to include)

These are all searched up to n=200,000 up to k<13372. http://www.noprimeleftbehind.net/cru...onjectures.htm and scroll down to 42. P.S. Good luck with k=13372. Also "fun" to search are k=1, 42 etc... unless you know how.

This is not correct!

CRUS is only searching for the least n for any k<13372 where k*42^n+1 is prime. Only the remaining 18 k-values where searched up to n=200k.
