313⋅2^2817751-1 is prime.
- and because the energy prices these days are 10x higher than normal, I'm going to suspend/stop search for prime numbers. In a way, this was a perfect end of my time here at NPLB. Maybe I'll come back if the world (and my bills to my local electric company) normalizes, who knows ? |
