Factor tables of this page will be updated in mid-January. Until then, contributions are kept on the web server. You can reserve numbers as usual. If you forgot your reservation keys, tell so by email.

My Pentium 4 processor could not withstand demanding programs and broke down. Take care for your CPU!

I'm afraid that I can't update this page for several days or a week because my computer crashed yesterday.
