Wow. The first primes on that base since n=24225. Congrats! :smile:

Wow... very nice primes!!! They are also quasi-repdigit primes!!!

No, they are not quasi-repdigit primes. To be such primes it must have ONLY two digits different from others ( example 4*10^n+1 = 400000.....0001) so has 4 and 1 ( two digits) different from all other zeroes :)
