A table to collect nominations for POTY 2022. Anyone please feel free to contribute missing entries, but discuss in the thread before changing an existing entry. Red text indicates entries that I (Macbi) want to check or improve.

Name (with link) Authors Description
1 74P34 mvr The first known non-trivial oscillator with period 34.
2 Raucci's p38 hotdogPi The first known oscillator with period 38.
3 Unsynthable still life Ilkka Törmä and kuluma
4 Speed Tunnel Kazyan
5 Explicit 15-glider Reverse Caber-Tosser MathAndCode, calcyman, simeks, Dvgrn, AlbertArmStain, Pavgran, Macbi, chris_c, dani, and Goldtiger997 A concrete construction demonstrating that any glider synthesis can be reduced to use just 15 gliders. The number of gliders was also reduced from its previous value of 17.
6 five new p23 engines Nico Brown (3), James Pascua (1), Mitchell Riley (1) At the end of 2021, only one period-23 oscillator was known, excluding variants: David Hilbert. As of the end of 2022, there are six.
7 CatForce oscillators The introduction of symmetric CatForce has led to new oscillators of approximately 112 periods, including fifteen primes above 13.
8 Engineered diehard A pattern that starts in a bounding box of area 9990, and yet lives for more than 10^10^10^10^10^10^10^10^10^10^10^10^10^10^10 generations before dying out completely.
9 Quartermax amling, HartmutHolzwart and Jason Summers A long-sought pattern that fills one quarter of the Life plane with zebra stripes.
10 Gliderless breeder, the p48 puffer for Gosper glider guns
11 20-cell quadratic growth

6G quadratic growth

23×13 quadratic growth

dani, AbhpzTa and Rocknlol The smallest known quadratic growth patterns, in terms of population (dani), number of gliders (dani), and bounding box (dani, AbhpzTa and Rocknlol).
12 Self-synthesizing glide-reflecting loopship Goldtiger997 A pattern made entirely of gliders that synthesises a reflected and translated copy of itself. Thus it makes an orthogonal spaceship travelling at a speed of 30985960c/144171206.
13 Speed Orthogonoid Goldtiger997 An adjustable spaceship capable at travelling orthogonally at any speed less than c/4.
14 Speed Orthogonal Loopship Goldtiger997 A pattern made entirely of XWSSes that synthesises a reflected and translated copy of itself. It travels orthogonally and is adjustable so that its speed can become arbitrarily close to c/4. It's population is much less than that of the Speed Orthogonoid.
15 Nico Brown's strictly volatile oscillators Nico Brown Nico Brown created a script that can create huge strictly volatile oscillators of any period 943+ except 944. Note that this entry does not include the strictly volatile p86, which coincidentally has Nico Brown as a co-discoverer.
16 Taco dexter1 The third known elementary c/7 orthogonal spaceship.
17 new honeyfarm catalysts, including chucklebait
18 component for adding a "crochet" to a c/3 spaceship
19 small Max predecessors
20 American Dream Ilkka Törmä and kuluma A pattern with finite population which has an infinite-population predecessor but no finite-population predecessor.
21 New spaceship syntheses Goldtiger997, mniemiec, INoMed, Kazyan, pipsqueek, muzik
22 New Reflector Periods vivi, iNoMed, Matthias Merzenich, David Raucci, Mitchell Riley, MAP bot, Tanner Jacobi, Noam Elkies
23 p24 glider gun cvojan, vivi, James Pascua
24 Lisp in Life woodrush A Lisp interpreter implemented in Conway’s Game of Life.
25 21-bit strict still life synthesis project and completion of the 20-bit pseudo still life synthesis project
26 New stable conduits and converters Several new stable conduits and converters, including but not limited to a glider-releasing H-to-R by Mitchell Riley; a small stable 180-degree reflector by Simon Ekström (the "Jubjub reflector"); F149, Lx129, HL224H, RSE14T117, NW-2T16,
27 p8 glider reflector Kazyan A period-8 180° glider reflector that works in every phase and hence can be used as if it were stable.
28 Soup search discoveries from distributed computing projects Charity Engine and Open Science Grid
