[quote=EdH;199536]I've moved 736950 over to a machine I have running continuously now. Let's see where it goes.[/quote]

I have it below 100 again. Does that mean I need to re-reserve it.:smile:

On an opposite note, I hope to finish 738936 by tomorrow. Is it of any interest that it has carried 2[sup]6[/sup] continuously from i1514 through the current i1941?

Take Care,
Ed

Your reservation for that number was moved to [URL="http://www.mersenneforum.org/showthread.php?t=11588"]the main reservations thread[/URL] some time ago.

If it was just 2^6, yes it would be, but unfortunately you've got 2^6 * 127, a perfect number driver. For more info on drivers, etc. see [URL]http://www.mersennewiki.org/index.php/Aliquot_Sequences[/URL] Perfect number drivers, especially the larger ones like 2^6 * 127, are very difficult to get rid of.

I was trying to find that info. Thanks for the link. I have it at 102 digits now, so I'll release it.

738936 is at i1949, c102, 2[sup]6[/sup] * 3[sup]2[/sup] * 73 * 127 * 457 * 617
