[QUOTE=XYYXF;440555][B]C284_135_127[/B] survived 20k+ curves at B1=300M. Maybe that's enough?[/QUOTE]A polynomial for it: [url]http://www.mersenneforum.org/showpost.php?p=441641&postcount=673[/url]

C284_135_127 is too big to be a 15e target, so I guess it's up to Greg whether he wants to use it on 16e. I am trial-sieving C242_129_101 and about to queue it up on 15e.

Whoops, sorry! C242_129_101 was factored by ECM. My apologies.

(reserved) [B]C229_148_70[/B] doesn't need t55 because of its low SNFS difficulty: 2[sup]8[/sup]·35[sup]148[/sup] + 37[sup]70[/sup] = 377·C229
