Enter your name and the numbers you want to reserve. This is helpful when you're planning on doing much work on a particular number, for example running SNFS on it. We don't want two people doing the same thing. If you're just doing ordinary work on no particular number then there's no need to use this page.

Write the numbers as k*2^n±1, one per line.

Reservations are automatically deleted after 120 days, but you can renew your reservation at any time by simply reserving the number again.

Your name:
