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

On an opposite note, I hope to finish 738936 by tomorrow. Is it of any interest that it has carried 2⁶ continuously from i1514 through the current i1941?

Take Care,

Your reservation for that number was moved to the main reservations thread 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 http://www.mersennewiki.org/index.php/Aliquot_Sequences 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, 2⁶ * 3² * 73 * 127 * 457 * 617

Take Care,
Ed

Reserving 738912.

Mini-Geek · 2009-12-23, 18:02

738912 has reached 100 digits and lost its driver (now has the downguide). Moving to main reservations...

biwema · 2009-12-23, 20:14

Done 736036

I just noticed 736036 merged with 315980 and 397600.

So 315980 is at size107, c100 now
