[QUOTE=Dubslow;471849]Other than the divisor of the inner term being wrong according to [URL="http://factordb.com/index.php?id=1100000000128028191"]FDB (should be 371330, not 79)[/URL][/quote]

The divisor is wrong, but not for the reason you state. It should be 71, not 79 - that's a typo - and the extra factor 5230 comes from the definition of phi_n.

Aha, obviously I'm not very well versed in cyclotomics. Forgot about the algebraic factor (mostly because it's more convenient when working with FDB and yafu). Thanks.

This was a 14e/33 job. 650M raw relations, 536M unique was oversieved; TD = 132 produced a density 88 (sparse part density 79) matrix of size 16.5M.

I would have requested 410M relations as 32LP; 650M at 33LP is faster to find (in seconds and in Q-range) than 410M at 32, and 650M was too many.

The power is reasonably reliable here. The machine is an i7-5820K with 32G memory, the job used all six cores and somewhere in the high twenties gigabytes of memory, for two and a half months.
