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.

Progress in the last 6 years has been nothing relative to the progress made in the period 19831989.
