574344
[QUOTE="Clifford Stern"]My efforts to obtain a new terminating sequence have hit a multi-year dry spell.
However, I managed to get a new merger today: 574344:i2514 = 5748:i15 = 246584 I think this is a new high (124) for a sequence before merging. I begain working on it August 9th when it was at 800. 2^2 * 3^2 sz 118. Please post this result on the Forum. I've done the upload to the database. -Clifford [/QUOTE] Congratulations to Clifford! |

End of quite a long drought
19494 ends at p=37 after 3417 iterations, maximum size was 120 digits at iteration 1547.
(if you're being pedantic, it probably merged with 11792 at iteration 3251) |
