QUEUED AS f86_143m1

(86^143-1)/6310004511640595245841714753155862187013059870305 from the extended Brent tables:

Sieve on 15e_small from 34M to 143M on the rational side. That should get 220M relations.

Test sieving 10k ranges:
Code:
  Q  yield
 34M 24221
 84M 20048
134M 17717
184M 16140
I also test sieved the degree 5 poly, but that's slightly slower.

I'll do the LA.
