139P7H1V0 is a c/7 orthogonal spaceship discovered by Caleb R. Hilton with qfind on April 17, 2024. Its front end contains two copies of a wave found by Park Shinhwan. It is the first known non-monotonic elementary c/7 orthogonal spaceship. A proposed name for this spaceship is motor grader.

Its two strong forward dot sparks allow it to run over a few still lifes and oscillators and remain intact. It's edge can also delete blinkers and gliders without affecting it; therefore, it is an edge-repair spaceship.

This spaceship shares any properties with bulldozer: They are both slow spaceships with a strong forward spark that can delete objects, they both have -e kinetic symmetry and bilateral symmetry, and they both have a population between 100 and 150.

139P7H1V0 running over some objects (click above to open LifeViewer)

On April 17, 2024, a partial 139P7H1V0 eater was made by Period1GliderGun and completed by Evin. It has a repeat time of 929. One day later, Luke Kiernan used CatForce to find a 139P7H1V0 to glider converter with a repeat time of 488. It has been greatly reduced by various other people.

Variants

It can be infinitely extended by supporting its own wave. It can also support other c/7 pushalongs; one of them is a half of Taco. Most of the pushalongs were discovered by Matthias Merzenich and Frank Everdij. One was found by Caleb R. Hilton.
