92*10^833852-1 is prime!

:bow wave:

 pepi37 2018-09-07 20:49

31521*2^1778899-1 (before 3 years) and today 663251*2^1778899+1 :)

 pepi37 2018-10-11 13:53

And today

84256*3^1778899+1 is prime! (848756 decimal digits) Time : 1329.140 sec.

After day and half
45472 *3^1778899-1 is prime!
:smile:
Now I have "pair" on base 2 and base 3
Hunt for primes on base 5 has started :smile:

Verification of new mega repdigit prime is started :)
But I am pretty sure it will be confirmed :)

93 · 10^[SUP]1029523[/SUP]-1 is prime :smile:

:party:
After nearly 2.5 years from my last mega ( also ) near-repdigit prime :smile:

From last mega prime to this mega prime I process only 9284 candidates :)
If we take some average number of candidates for one mega prime (38000 on 1e15 as sieve depth) , I was very lucky since I found two in this range.
