Revision as of 07:58, 21 September 2025

PK22 is a Life enthusiast.

About me

I am interested in cellular automata, mainly CGOL. I have discovered/reduced some syntheses, mainly those of still lifes. I enjoy contributing to Catagolue. I can write programs in Python, but have yet to write any significant search programs.

How I discovered CGoL

In late 2023, I was working on random short Python projects to improve my programming ability, and Conway's Game of Life happened to be one of these. Normally I would move on from a project once done, but it prompted me to do more research into CGoL, and I discovered LifeWiki fairly soon after that. I joined the forums roughly a year later.

Discoveries

  • March 16-17: I found syntheses for three lakes with no known synthesis.[1][2][3] These were my first posts on the forums.
  • March 22: I reduced the synthesis of the regenerative loop to 18G, down from 29G.[4] It has since been reduced to 14G.
  • April 29: I constructed a dimer of BTS in 22G.[6] At the time, this was only slightly significant, but the catalyst was later used by Chris857 to create a synthesis for a stator variant of Honey ring on August 5.[7]
  • May 3: I found a synthesis for a commonly used stator variant of 31.4 in 53G.[8]
  • May 13: After it occurred in one of my G1 hauls, I created a 13SL 1G seed for tempest.[9]
  • July 12: I found a synthesis for a stator variant of Jason's p11 in 36G.[10]
  • August 15: Using a reaction from Pseudo_D4_+1_Test, I proved that even without RCT technology, any 2xN block array is constructible in ≤ 2N+3 gliders.[11] On August 26, I found a more efficient method, meaning all but four arrays are constructible in less than one glider per block. [12]
  • August 29: I found a 26G synthesis for a stator variant of Airforce, 10G cheaper than the canonical version.[13]

Catagolue

My user page: PK22

I uploaded my first hauls in January 2025,[14] initially using apgsearch v1.x and later with the precompiled version 5.x.

Currently, I have three badges: Trillionaire, Sprotsmanship, and Limitless.

My most significant discoveries are new 35[15], 36-cell[16] and 37-cell[17] still lifes, the eighth natural occurrence of tempest.[18], and a new natural infinite growth pattern[19].

OCA

I am interested in OCA, but not as much compared to CGoL. See User:PK22/B36n7eS2-i3 for information about a rule I discovered.

I am also heavily involved in the exploration of B3/S23-a5 - see User:PK22/OCA:Travelling Ts.
