After months of being left in the dust (from 163716):
Code:
930 . 6051850250660733888778970014396919144105159828091724572420308956844196330422742462942206183898797421352490073343953196 = 2^2 * 13667260733773 * 20448544097532025062245003 * 5413576893035020798243708443322934991599394274129812009005704297339255398292421 931 . 4538887687996325314944986277953849439939403995187842914443916105517409173529018067021095175418669685006067566807564388 = 2^2 * 1134721921999081328736246569488462359984850998796960728610979026379352293382254516755273793854667421251516891701891097 932 . 3404165765997243986208739708465387079954552996390882185832937079138056880146763550265821381564002263754550675105673298 = 2 * 379 * 27701 * c111 |

195528 is at iteration 7430 (no, there is no typo here!)
at this point with 2^2 * 7. It reached 12-digit bottom, twice; didn't merge with any deposited sequence; it would be worth-while to check C9C30 database! Frank, do you have the tools for that? |

Edit: no side-sequence. ![]() Quote:
130396 has recently come REALLY close to escaping the driver - it was 2 * 3^2 * p, but the prime was of the wrong form.

Barring a merge, gentlemen, I present you the longest single sequence.
(In the background, I ran some primality tests on all the factors in the sequence; they checked out.) |

That's not
. that's ! That easily surpasses everything that I have listed on my sticky note here. And at <100 digits, there's a good chance of adding even more lines with an escape from 2^2 * 7!1578 was holding the record at 7260+ for the longest single sequence.... |

That's because I didn't realise it was the longest single sequence. It would still have been the longest single sequence unless there was a merge (as opposed to side-sequence).
