1 remain

73187*6^619238-1 is prime. 481866 digits.
This is quite a lucky find, as it was the lowest-weight k in R36.
31 k's remain in R36.

Nice find. Congrats!

32 k's remaining for R36 counting k=9582 that Masser is working on in conjunction with R6. :smile:

Whoops! Thanks for correction: 31 k's that I am working on, and 1 that Masser is working on. :)

Nice!!! You solved k=2 for the smallest Sierpinski base with k=2 remain!!!

:bow wave::bow wave::bow wave:

Next Sierpinski base with k=2 remain is S365.
