44P5H2V0

44P5H2V0 is an unnamed 2c/5 orthogonal spaceship discovered by Dean Hickerson on July 23, 1991,[1] being the first 2c/5 spaceship to be found. Robert Wainwright and David Bell then found some small tagalongs that allowed the creation of arbitrarily large 2c/5 spaceships. These were the only known 2c/5 spaceships until the discovery of 70P5H2V0 by Hartmut Holzwart on December 5, 1992.[2]

gollark: Also lol no generics.
gollark: It's very hostile to abstraction.
gollark: Golang: BAD.
gollark: It works if you enable the legacy bound checking switch/
gollark: How is v3.1 cursed?
