[QUOTE=Batalov;241502](and other messages similar to that)

Was this [URL="http://mersenneforum.org/showpost.php?p=166068&postcount=1"]work distribution map[/URL] thrown out of the window then?
I somehow always thought that [B]97[/B] < 100, 84 < 100...[/QUOTE]Yes, actually, it was, kind of. Wieb Bosma never got back in touch with us on uploading his data to the factor DB, so we (bchaffin and RobertS, mainly) had to go out and recreate it....no choice, really.

We also found terminations that he may have found previously, but since he hasn't updated his status pages since last year, we knew nothing of....

Last one for the year?
 
10 metreh found this one:[code]645428:i1959 = 354204:i83 = 3279634[/code]Nice drop: all the way down to 7 digits!

First for the year!
 
Looks like Clifford gets the first termination for the year!

233502 terminates in 347.

[QUOTE=RobertS;251900][URL="http://factordb.com/aliquot.php?type=1&aq=373152&big=1"]373152[/URL] terminated :smile:

max height at i375: 112 digits![/QUOTE]Actually, I think this might be chalked up as a merge, rather than a straight termination......[code] 1017 . 215626 = 2 * 131 * 823
1018 . 110678 = 2 * 55339
1019 . 55342 = 2 * 7 * 59 * 67
1020 . 42578 = 2 * 61 * 349
1021 . 22522 = 2 * 11261
1022 . 11264 = 2^10 * 11
1023 . 13300 = 2^2 * 5^2 * 7 * 19
1024 . 21420 = 2^2 * 3^2 * 5 * 7 * 17
1025 . 57204 = 2^2 * 3^2 * 7 * 227
1026 . 108780 = 2^2 * 3 * 5 * 7^2 * 37[/code]I'm not sure which one it merged with, though.....I need to do a little more research.
