Number	Name (with link)	Authors	Description
01	B2n3-enqy4cijrwyz5cinqy6kn78/S01e2ein3eikry4-ciry5-aeky6ein7e8 and its variants (https://conwaylife.com/forums/viewtopic.php?f=11&t=6749)	Hibiscus	The original rule has tons of high-period oscillators, often with simple predecessors. Its variants also have many oscillators, which might mean that there are some gems hidden in one of these rules.
02	New spaceships in life-like cellular automata (https://conwaylife.com/forums/viewtopic.php?f=11&t=1074)	Many	Highlights include a spaceship in B35/S46, one of Eppstein's Most Wanted (May13), a 2c/11o spaceship in B356/S456, the first spaceship of that speed to be found since 2017 (hibiscus), and several spaceships in B3567/S14578[1], the rule with the most spaceships (May13 & H. H. P. M. P. Cole), bumping the speed count to 25 different spaceship velocities.
03	Omniperiodicity	Many	No general thread for this entry, but in 2024 several rules were proven omniperiodic, including Dancing by the slug, Bazaar, B34c/S234c, and a few other rules.
04	Speciation (https://conwaylife.com/forums/viewtopic.php?f=11&t=6492)	NimbleRogue & H. H. P. M. P. Cole	The rule with the 2nd most amount of NRSS of any INT rule. The rule with the most amount of NRSS is a relative of this rule.
05	Project Omniraumschiff (https://conwaylife.com/forums/viewtopic.php?f=11&t=6541)	Hibiscus et al.	A collaborative effort started by me which attempts to gamify the process of shipsearching and increasing the number of spaceships known in Eppstein's Glider Database.
06	BasiKnight (https://conwaylife.com/forums/viewtopic.php?f=11&t=6715)	islptng	A very versatile rule with small (2,1)c/6.
07	Weird spaceships (https://conwaylife.com/forums/viewtopic.php?f=11&t=3120&p=200111#p200111)	NimbleRogue	Weird series of spaceships in an isotropic non-totalistic CA
08	Foam rules (https://conwaylife.com/forums/viewtopic.php?f=11&t=6649)	Many	Weird rulespace where cells surrounding an empty space (foams) often form.
09	Ada's rule (https://conwaylife.com/forums/viewtopic.php?f=11&t=6777)	LuveelVoom (?)	A surprisingly interesting rule for having only three non totalistic transitions and being otherwise totalistic.
10	Engineered spaceships in Sticky (https://conwaylife.com/forums/viewtopic.php?f=11&p=186004 https://conwaylife.com/forums/viewtopic.php?f=11&p=196753)	islptng	Engineered 106c/23932o and 64c/9896d in Sticky.
11	Engineered replicators (https://conwaylife.com/forums/viewtopic.php?f=11&t=6577)	islptng	Engineered replicators in various rules, including a fast one, a 4-state one, and one that prints itself but black-white reversed.
12	17-state Moore RuleLoader solution for all R2 Moore 2-state rules (https://conwaylife.com/forums/viewtopic.php?f=11&p=198888), 77-state vN RuleLoader solution for Factorio (https://conwaylife.com/forums/viewtopic.php?f=12&p=193435), and life simulaton with single cell representing 2x2 areas (https://conwaylife.com/forums/viewtopic.php?f=12&p=193807)	islptng	17-state Moore RuleLoader solution for all R2 Moore 2-state rules, 77-state vN RuleLoader solution for Factorio, and Life simulation with single cell representing 2x2 areas.
13	photons10	CARuler	A 220-state rule with photons in 31 oblique velocities besides orthogonal and diagonal. There are also many interesting things besides photons.
14	Various 3-state rules with special features(https://conwaylife.com/forums/viewtopic.php?f=11&t=6458)	FWKnightship
15	CataProp family	B-engine, others	A family of mainly 3-state isotropic rules with a common property that there's a common spaceship and have reflectors, eaters and splitters for it.
16	Life-like p1 photon project (https://conwaylife.com/forums/viewtopic.php?f=11&t=6756)	Matthias Merzenich, Keith Amling	This is a project started by Matthias Merzenich in 2024 to determine which Life-like CA support period-1 photons. During this project, Keith Amling developed several new search techniques that allowed both the discovery of new p1 photons and the disproof of their existence in many rules. Only 105 rules remained unsolved at the end of 2024.
17	High-period photons (https://conwaylife.com/forums/viewtopic.php?p=194756#p194756 https://conwaylife.com/forums/viewtopic.php?p=194774#p194774 https://github.com/Aaron-d-k/mpps)	mystical	These are photons with periods above what had previously been practical to search for, found with mystical's new multi-period photon searcher program.
18	c/3 diagonal moon rake in Seeds and (2,1)c/4 knightrake in B25678/S4578 (https://conwaylife.com/forums/viewtopic.php?p=192202#p192202 https://conwaylife.com/forums/viewtopic.php?p=198763#p198763)	Keith Amling, Matthias Merzenich, Dmitry Maitak	These are low-period rakes of unusual speeds in Life-like CA.
19	Asteroids (https://conwaylife.com/forums/viewtopic.php?f=11&t=6759)	R2INT	A near-explosive rule featuring six natural spaceships of five speeds and a c/4 growth pattern that computes OEIS sequence A133463. Numerous rakes utilizing these engines have been developed, primarily by R2INT.
20	A rule with 24 nonadjustable slopes(https://conwaylife.com/forums/viewtopic.php?f=11&t=6352&start=25#p194300)	FWKnightship	This rule by has 31 NRSS, and 24 nonadjustable slopes of ship. The base ship in this rule is a 2c/36d failedrep leading to interesting behavior when multiple are combined.
21	Oscillator offset ship(https://conwaylife.com/forums/viewtopic.php?f=11&t=3120&start=925#p178200)	NimbleRogue	This pattern is a ship where for most of it's lifetime it is just a rectangle with a p550, and p446 oscillating reaction on either side that slowly go more and more out of sync until it break.
22	snrship(https://conwaylife.com/forums/viewtopic.php?f=11&t=6710)	Moosey	This rule supports a ship with a period of ε0, and many other incredibly high periods. It also has some lower period ships as well.
23	Corderization of a (21,6)c/177 in B37e/S238 (https://conwaylife.com/forums/viewtopic.php?p=191293#p191293)	Naszvadi	This puffer was previously known, but lacked corderization. AbhpTza subsequently reduced the ship to a 7-engine form.
