If we're adding scores for enormously large numbers, there's also this paper which gives a polynomial for RSA768 (232 digits) with score 7.690e17, better than the original poly used for this number.
RSA230 and RSA232 have both been factored but I couldn't find the polynomial for either.

Notes in the announcement of RSA232 being factored mention plans to publish the details in a “forthcoming scientific paper”, so we will just have to wait on that. Last fiddled with by swellman on 20211203 at 16:57

The recent interest in older RSA GNFS polys has caused me to relook at some of the older more conventional factorization records.
I located one job involving a C212 cofactor of 10,770M, factored by frmky back in Sep 2013, though the deg 5 poly itself was found in June 2013 by Gimarel per this post. Gimeral’s poly was used by frmky in the factorization. The confirmed escore is 6.698e16, considerably better than the current listed deg 5 record for a c212 (6.435e16 in Nov 2015 on another factorization job seemingly by frmky?). Unless I’m mistaken here, the c212 record score needs to be updated once someone confirms my findings. Last fiddled with by swellman on 20211212 at 15:25

More searching through old posts of the forum turned up another high poly score.
Gimarel found a poly score of 2.263e13 on a C175 back in Dec 2015. This is the record score for C175. The table should be updated  can someone else confirm this finding? TYIA.

What you're doing is what I did to start this table just make the updates with any poly you find. I don't doubt that I made some mistakes!
The only ones I intentionally omitted were when someone 'spun' a poly after the factorization job was run I don't think setting new records on previously run jobs is a good idea. Though for RSA numbers, I think new poly searches are a worthy way to measure current tools / techniques against previous stateoftheart.

Sometimes forum members would alert me to errors in table, though now not for many months. Last fiddled with by swellman on 20211212 at 04:30

Although not containing specific values generated by msieve perhaps this PPT presentation may provide an assist in reviewing prior approaches and developing new ones. There are other papers of this kind and quality but this one is succinct.

I'm working on a promising alternative method where such published work provides some solid guidelines which can be transformed into other forms and the results compared accordingly. Any possible source of insight to a vexing question is always welcomed. Last fiddled with by jwaltos on 20211213 at 04:26
