Default Base 2 to 768 bits

Hi,

An ECM "near" miss:

2,1526L C191 = p53.p138

p53 = 81100940490524995434296633553178345665740792232320957
p138 = 189340478259936307556926821084538798956773594080872930492012919670535867070173114738309353256564597114834763985330229063415837545856579093

This finishes ALL of base 2 to 768 bits.

The linear algebra for 5,314+ is in progress and 6,281- is sieving.

All the Cunningham numbers of less than 768 bits are now base 5, 6, or 7, with only 18 entries left. And it looks like work has already started on seven or eight of these numbers. I started ECM on Cunningham numbers six years ago, and am amazed at the progress made since then.

Two of these (5,319- and 5,329-) are rather easy.

Nothing specific. Just to work on numbers that accessible with
my resources. Numbers among the first 5 holes get preference.

Progress in the last 6 years has been nothing relative to the progress made
in the period 1983-1989.
