Long-lived methuselahs

[NickGotts]

Cross-posted from "Systematic Survey of Small Patterns".

Here are two more variants of bunnies10a (10-cell single-cluster patterns that last 17425 steps). The one on the left has a bounding box 7*5, and an MCPS of 11, which according to the usual criteria for methuselahs makes it the preferred variant.

Code: Select all

x = 27, y = 5, rule = B3/S23

Another slight improvement (in terms of life-span) to bunnies10. Let's call this one bunnies10b: lasts 17431.

Code: Select all

x = 9, y = 6, rule = B3/S23
o$bo$2bo$3bo$2b2obo$6b3o!

Bounding box 9*6, MCPS 11.

Here's an alternative form - the two have the same immediate successor:

Code: Select all

x = 9, y = 6, rule = B3/S23
o$2bo$bo$3bo$2b2obo$6b3o!

Same bounding box, but MCPS of 13.

Step 29 of bunnies10b is the same as step 23 of bunnies 10a.

Presenting the B-pair Switchuselah (sorry for necropost):

Code: Select all

x = 43, y = 60, rule = B3/S23

I'm going to this thread since it's the only topic relevant to my post.

I've been trying to make methuselahs that try to continue evolving NOT based on pure random chaos:

Example 5625M:

Code: Select all

x = 20, y = 20, rule = B3/S23
7b3o5b3o$7bo9bo$8bo5b3o$10b2o$11bo2$8b2o$3o5b2o$o6bobo$bo4b2o4b2o$3b4o
bo4bo$4b2o12b2o$8bo8b2o$7bobo7bo$7bo8b2o5$16b3o!

What I've been trying to make is a pattern that tries to "prolong its evolution" through the use of gliders.

What I need is a fusestretcher (crab is the smallest example) and a pattern that lingers around before hitting the extended boat/barge.

If I can find a pattern that lingers for 8,000 generations before hitting a barge:

Code: Select all

x = 2011, y = 2015, rule = B3/S23

This is a Genuine Methuselah Soup, 7060gens- Thank You for posting !
Also, it really is full, and I mean chock full, of so many surprises you will want to watch it again !
( need to make a list of all the goodies )
This one may be the best I have ever seen -
since it makes so many things, it is full of INFO
so it is worth playing with, perturbing, etc.

BTW -
