### New spaceship velocity

Matthias Merzenich has discovered a c/7 diagonal spaceship -- the first of its speed. This raises the total to thirteen reasonably-low-period spaceship velocities, specifically eight orthogonal (c/2, c/3, c/4, c/5, 2c/5, c/6, 2c/7, 17c/45) and five diagonal (c/4, c/5, c/6, c/7, c/12). Of course, an infinite number of spaceship velocities are known, as the *Gemini* can be adapted accordingly.

Moreover, Matthias has actually discovered an infinite family of such spaceships, as one of the frontal components can support itself to yield an extensible spaceship.
