I'll take C167_P242_plus_1 next.

P.S. Does C212_121_69 need a little touch up to get it to 110+M?

I'll take C171_133_48 next.

It's been awhile since a post processed a 31 bits task specially with difficulty above 250. Last time I used university Xeon 8 core server and it took 10 days. How long would take 13_227_minus1 to be processed on a quad core machine running a 3.2 GHz?

I'll take 47_161_minus1 next.

P.S. I should complete this before going out of town.

C171_133_48 factored
 

14 hours to solve a 4.7M matrix on a Core-i5, -t 4 using target_density=116 (TD=120 failed).
(Interesting SQRT phase.)
