User:Macbi/POTY2022 Nominations

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, made by adding cvojan's traffic stop as fenceposts for a known wick by Jason Summers.
3	Unsynthable and limited-ancestor objects	Ilkka Törmä and Ville Salo	Discoveries include an unsynthesizable still life and unsynthesizable p2 oscillator, both based on "self-forcing" agars, as well as a generalized solution to the grandfather problem (patterns that have n-tick predecessors but no (n+1)-tick predecessors).
4	Speed Tunnel	Kazyan	A stable glider-to-Herschel converter with a repeat time of 61 ticks, faster than the syringe's 78 ticks.
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 "crotchet" to a c/3 spaceship	Goldtiger997	This is a new synthesis component that can repeatably extend a "waltz" section of c/3 orthogonal spaceship, allowing for the first known infinite series of synthesizable c/3 spaceships.
19	small Max predecessors	Rocknlol, iNoMed	After an intermediate 127-cell, 27×23 new record set by iNoMed, the smallest predecessors of a Max spacefiller variant by population and bounding box are currently 110 cells and 21×21, respectively -- two different patterns, both found by Rocknlol.
20	American Dream	Ilkka Törmä and Ville Salo	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	Glider construction recipes were discovered for Orion 2, 33P4H1V1, 70P5H2V0, 58P8H4V0, 30P3H1V0, 29P3H1V0, brain, 66P5H2V0, and 37P4H1V1, as well as the unbounded number of c/3 spaceships made possible by #18 above.
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	A new second-smallest glider gun after the Gosper glider gun, fitting in a 20 × 20 bounding box.
24	Lisp in Life	woodrush (Hikaru Ikuta)	A Lisp interpreter implemented in Conway’s Game of Life, using technology similar to the Quest for Tetris project. This is the first implementation of a standardized high-level programming language inside 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
