Methulesahs with the biggest final populations

[Azerty]

Hello, I created this topic because I wanted to make a list of the n cell pattern that make the biggest final population in cells.

If you discover a pattern that could replace another pattern or get added to the list, you can submit it below by putting it's RLE text.

Here are the rules:
- Infinitely growing patterns are not allowed, except if they eventually get destroyed (eg. a glider hit the engine).
- Only the final population count. The lifespan and the hitbox don't matter.
- The starting pattern must fit in a n x n bounding box where n is equal to the number of cells the pattern contains.
The maximum bounding box size is here to prevent people from building an infinite growing machine and put a stable pattern very far away to destroy it.
- If the final population contains oscillators or spaceships that change population (eg pulsars), only the maximal population, the minimal population does not.

Current winner patterns and their final population cells count:
1. 0
2. 0
3. 4 cells (pre-block)

Code: Select all

x = 2, y = 2, rule = B3/S23
o$2o!

4. 12 cells (T-tetromino)

Code: Select all

x = 3, y = 2, rule = B3/S23
3o$bo!

5. 116 cells (R-pentomino)

Code: Select all

x = 3, y = 3, rule = B3/S23
o$3o$bo!

7. 633 cells (acorn)

Code: Select all

x = 7, y = 3, rule = B3/S23

I created this topic because I want to make a list of the n cell pattern that make the biggest stage population in cells.

Looking through List of long-lived methuselahs, here are some candidates:

• multum in parvo, acorn: initial population 7, final population 633
• 7468M: initial population 8, final population 952
• Bunnies: initial population 9, final population 1744
• initial population 10, final population 3611:

  [...]

  Code: Select all

  x = 39, y = 78, rule = B3/S23
  3o2b2o$3bo$5bo75$36b3o!
  

  [...]

• 24827M: initial population 13, final population 5151

I added the 24827M pattern but I didn't added the 10 cells one because the bounding box of is too large.
The acorn, the 7468M and the bunnies were already in the list.

What about this:

Code: Select all

x = 235, y = 189, rule = B3/S23
28$52bo$52b2o111$175bo$173bob2o$173bobo$173bo$171bo$169bobo!

for >12, it is infinite.

This was specifically disallowed by rule 3. It has a bounding box much larger than 13x13.
