367^51, 53, 55, 59, & 61 terminate

I'm still working on 367^57. It's a tough one for such a small starting size. No other work on this base.

I'm just now starting on base 373.

I'll try to catch this up in the morning. You did notice I completed the three I mentioned a couple posts ago?

Yep. Squeezing those in on the other machines while base 373 hums away on the Ryzen. Busy day at the office. :-)

23^123 terminates

Base 23 is complete!!

It's great to have a base finished that was expanded to 125 exponents a few months ago.

This was a most unexpected development. For a long time, it looked like back-to-back hard C136s. You split the first one so I was going to go ahead and split this one but I got lucky. ECM came through at the last minute with a P42 that ended up in a 3-way split. 3 indexes later it dropped the factor 3 and then it dropped 15 digits over the next 2 indexes and that's all it took. Easy-peasy after that.

Alas, I'm not off the hook so easily. 307^63 also came up with a C136 on the index after you split the C140. This one held tight through full ECM. At 149/136/3, its size is small enough that I'll continue with it hoping not to get a C>=140.

Yes, this is wonderful !
Thank you very much to you !

373^51, 53, 57, 59, & 61 terminate

I'm still working on 373^55 as well as 367^57 from yesterday. No more work on exponents 63 or 65 for either of the new bases.

From the splits, I'm still working on 307^63 and 1184^54.

Almost everything coming up with tough cofactors here but not so tough that I won't keep going with them.

373^55 terminates

I'm done with base 373.

EdH · 2022-10-09, 02:16

Let's play with some ^63s and a couple ^65s:

Code:

373^63: 160/141
367^63: 159/145
347^63: 151/148
359^63: 156/154
373^65: 161/159
367^65: 163/161

367^57 terminates

Releasing 1184^54 at 146/143/3/full.

Worked and released 373^63 at 160/152/3/t40.

gd_barnes · 2022-10-09, 22:52

359^63 terminates

Base 359 is complete!

I finally got one of these exponent 63 thingies to cooperate. They've been a pain.

There's a lot going on so here's a status:

From your recent ^63 & ^65 splits:
373^63: 160/152/3/t40 released; reported this morning
367^63: 159/136/3/full released
347^63: 149/147/109/t40 still running full ECM and has passed t40; will release if it doesn't split.
359^63: terminated per last post
(last two have not split yet)

From your previous splits:
307^63: 141/129/3/full still working on a very long-running one; will take it to termination.

From the index 1 effort:
1155^51: 142/140/11/full still working; will take it to termination.

New bases 888 and 1264460; just getting started:
Base 888: ^50 & ^52 will need some work but I will work towards termination on them.
Base 1264460: ^26 is at 159/128/3/full so I'll split that but I don't anticipate continuing much more. ^28 & ^30 have had their typical ECM run on them. Nothing there.
I'm also initializing opposite-parity sequences on both bases.
