People who like the prime testing style of 321 are welcome to joing our Riesel Prime Search project searching for primes of form k*2^n-1. We have manual reservations and use LLR only. Everybody is free to test the numbers he/she likes.

Well sieved values in the megabit prime region (n>1M) are available right now for k=5, 15, 17, and 105. Presieved candidates for many k<300 and n<1M organized in so-called "drives" are available as well. Feel free to drop by and have a look.
