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.
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 12: I constructed a 16SL 1G seed for a Coe ship, based on a 5SL dirty seed by TigerCub414.[5] On April 17, I reduced this to 12SL.[5]
Catagolue
My user page: PK22
I uploaded my first hauls in January 2025,[8] initially using apgsearch v1.x and later with the precompiled version 5.x.
Currently, I have two badges: Trillionaire and Sprotsmanship.
My most significant discoveries are new 35[9] and 37-cell[10] still lifes, and the eighth natural occurrence of tempest.[11]
Pseudo_XX_Test
On July 10, 2025, I published a hacked version of apgsearch v1.1 that featured, among other things, support for new 'pseudo-object' symmetries.[12] So far, these symmetries (in the form of 'Pseudo_<symmetry>_Test') have helped to reduce a few syntheses for pseudo still lifes. The latest version of the script is maintained at User:PK22/apgsearch v1.1 Py3, and I would appreciate some help with searching, particularly for the pseudo-object variants of D4_+2, C2_2, and C1.
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.
