- Not to be confused with wing (spaceship).
27P4H1V1 (or wings[1]) is a c/4 diagonal spaceship found by Jason Summers on September 13, 2000.[2] It consists of two gliders pulling a small tagalong.
A 64-glider synthesis for 27P4H1V1 was found by Goldtiger997 on October 28, 2019.[3] This was reduced to 42 gliders over the next few days due to optimizations by various people,[4] and was reduced again to 31 gliders in December.[5]
Nicolay Beluchenko found various tagalongs for 27P4H1V1 in September 2005, as shown below.
