Congrats!

This time an announcement for myself. Looks like the smallest k of the whole project was finished:

254*5^911506-1 is prime

Lets see what the officials have to say about it.

Congrats Lars on a monster top-100 prime! :smile:

For historical reference and accounting purposes both here and at CRUS for Riesel base 25, I should state here that this prime actually knocks out k=158750 for bases 5 and 25 because:

254*5^4-1 is prime
1270*5^3-1 is prime
6350*5^2-1 is prime
31750*5^1-1 is prime

-- and now since n must be >= 1 --
158750*5^911502-1 is prime

-- and finally for CRUS --
158750*25^455751-1 is prime

Congrats again! :-)

Oops. You meant 128552*5^525537+1

:redface: Oops my fault. You are right.
But the wrong one would have been a real finding. :cool::wink:
