35P4H1V1 is a c/4 diagonal spaceship discovered by Hartmut Holzwart in September 2004. Among all known c/4 diagonal spaceships it is the tenth smallest. It consists of two gliders pulling a tagalong behind them.
Unlike many smaller c/4 diagonal spaceships, it is completely time- and space-asymmetric. There are only four c/4 diagonal spaceships smaller than it with this property, namely B29 and the three different ways in which a glider can follow a B29. It is the smallest fully asymmetric tagalong for two gliders.
Glider synthesis
35P4H1V1 was first synthesized in 41 gliders by KtT on July 24, 2025, based on a final step by Goldtiger997.[1][2] At the time, it was the smallest known unsynthesised spaceship.
