QUEUED AS f38_158p1

(38^158+1)/2275019624642515721256024045199705 from the Brent tables:

Sieve from 40M to 110M on the algebraic side (this should be suitable for 15e_small).

Test sieving 10 ranges:
Code:
  Q  yield
 40M 29339
 80M 22756
120M 24926
160M 19584
200M 20554
I'll do the LA.

I'm hoping 15e will produce a smaller matrix than 14e with 3LP would.
