I'm sure other people have tried factoring these numbers that would be tested by the 31337 prp account.
I didn't want people to double effort so I started a thread mainly b/c I did one factoring fairly deep for the dropped test, no factor found.
sbfactor 10223 13467677 1000000 2000000 200
It didn't take very long to complete the test few hours for sure, I was running other programs in the backgroud at the same time however.
If anyone considers factoring these numbers I would suggest you try numbers that are very very deep for B1 and B2. I was only going to do stage 1 with b1=b2=1000000 to see what happens but stage 2 seemed pretty fast with these bounds, I'll update.
If I understand correctly B1=B2=1M is better than any B1<B2 with B2=1M
I.E. doing
sbfactor 10223 13467677 1000000 2000000 200
and stopping after stage 1 is better than any
sbfactor 10223 13467677 xxxxxx 1000000 200 full test with stage 2.
Correct me if I'm wrong and suggestions for b1, b2 values for those attempting factoring.
