Linear algebra reservations, progress and results - Page 51

Since my role in factoring 4051^71-1 has so far been limited to poking and prodding others to commit their own resources, the least I can do is reserve it for post processing.

Edit: Oh wait, will it fit in 16 GiB...? I don't do large factorizations anywhere near enough to recall the answer of the top of my head

Yes it should fit easily in 16 Gb.

Neat. In that case, assuming that no one has reserved C175_4788_5241, then I would like to post process that one as well.

Three-way split, which is a little unusual

Sixteen or so hours for 5.3M matrix on i7/4790K, but don't believe this time because I forgot to stop mprime for the first few hours.

Indeed, though Rich Dickerson also had a 3-way split yesterday for GC_3_475 into p62 * p62 *p66.

Curious that adjacent entries in the 3+ table should behave like that.
