2c/7 orthogonal is a speed that is equivalent to two sevenths of the speed of light.
Spaceships
The first 2c/7 spaceship discovered was the weekender, which was found by David Eppstein on January 12, 2000 using his search program, gfind. On April 27, 2000, Stephen Silver discovered a tagalong that can be pulled by two weekenders.[1] Attaching these tagalongs to weekenders is currently the only known method of constructing other 2c/7 spaceships.
Puffers
No 2c/7 puffer technology is currently known.
