A currently unnamed (34,7)c/156 spaceship was constructed by Luka Okanishi and finalised on 6 June 2023.[1] It is an oblique spaceship based on the (34,7)c/156 Herschel climber.
Properties
In its minimum phase, this spaceship has a population of over 25 million active cells, which is more than double that of the caterpillar, the first engineered spaceship which is also crawler based. In terms of bounding box, it is also perhaps the largest interesting pattern, surpassing constructions such as the Spartan universal computer-constructor as well as other spaceships such as Gemini and the self-synthesizing oblique loopship.
With a period of 156, it also has the lowest known period of any crawler-based engineered spaceship known so far; the 17c/45 orthogonal caterpillar has an overall period of 270, and the (23,5)c/79 waterbear has a full period of 158.
It is the first new velocity for a crawler-based spaceship to be discovered since the waterbear in 2014; while the silverfish had been constructed in 2020, it was merely an improvement to the known velocity of 31c/240 orthogonal.
The overall morphology of the spaceship has also been highlighted as remarkable, given that many other macro-spaceships resemble basic lines when zoomed out.[2]
History
The (34,7)c/156 Herschel climber was originally discovered by Dave Greene in April of 2013.[3] Sphenocorona rediscovered the reaction independently in September of 2014 in the context of reactions usable for engineered spaceships.[4][5] A dedicated thread on the ConwayLife.com forums was started in 2016 to compile prior mentions of technology related to this fuse as well as to further discussion on a potential spaceship, although this remained largely inactive until early 2019.
