Open sequences: 9253 Of these, there are 480 that are less than 500 lines and 21 that are over 6000 lines. There are 8419 that are under 120 digits and 58 that are >= 150 digits. My first thought was to open a Project 500 after Project 400 ended, but based on how long it took to move everything to 400 lines, that's probably not viable. We could, however, keep a sticky with the shortest sequences and we could move the lower end up on an ongoing basis. One of the past projects was an effort to work ranges up to 110 digits. We could start a 120 digit project, but it would be a very significant investment of time and effort. A project to try and pull something else up to the level of 933436 would be interesting, but everything that is anywhere close is not going to work unless there is a driver escape: Code: 842592 8003. sz 172 2^3 * 3 * 5 * 13 * 587 * 823 * 1627 195528 8017. sz 144 2 * 3^4 * 24110979082363 552150 8197. sz 147 2^2 * 3 * 7^2 * 17 * 953 * 16493 453798 8565. sz 148 2^2 * 7 933436 12320. sz 150 2^2 * 7 * 349 * 798258469 Another intersting long term project might be to see how high we could push the highest sequences: Code:  564 3357. sz 172 2^2 * 7 * 31 * 103 * 6211 * 26557 842592 8003. sz 172 2^3 * 3 * 5 * 13 * 587 * 823 * 1627 2340 688. sz 174 2^3 * 3^2 * 5 * 13 * 34522914553 8352 1716. sz 175 2^2 * 3 * 5 * 7 * 88237 * 11918034727 3270 645. sz 177 2^5 * 3 * 7 * 73 966 893. sz 178 2^2 * 3^2 * 5 * 83 * 2099 162126 4283. sz 178 2^3 * 3 * 5 * 461 552 1057. sz 179 2^2 * 3 * 71 * 145633 660 890. sz 181 2^3 * 3^2 * 5 Interestingly enough, 842592 is a member of both sets, long and high....if unconnected gets tired of working it, we could adopt it as another community sequence.
