I’ve enqueued this as posted (with some slight reordering of the lines), but are you sure about 3 LPs on the rational side while sieving on the algebraic side? It can be changed until it is thrown...

In test sieving I first ran this as a 31-bit job and the yield was great. Would have been a perfectly fine way to sieve this job. But the upper end for 14d is 165-170, a 15e_small at lpba/r of 30 is...

The c175 of i1723 is running ECM up to t55 on my local machine. Should finish tomorrow night.

Found a decent polynomial which I’ll enqueue on 15e_small once ECM is done.
