**c/5 diagonal** is a diagonal speed that is equivalent to one fifth of the speed of light.

## Spaceships

The first c/5 diagonal spaceship to be discovered was 295P5H1V1 and was found by Jason Summers on November 22, 2000.^{[1]} No other spaceships of this speed were discovered until January 8, 2005, when Jason summers found the much smaller 86P5H1V1. In July 2006 Nicolay Beluchenko discovered three new c/5 diagonal spaceships, including the asymmetric 67P5H1V1.^{[2]} The smallest known c/5 diagonal spaceship, 58P5H1V1, was discovered by Matthias Merzenich on September 5, 2010.

## Puffers

The first c/5 diagonal puffer was built by Matthias Merzenich on September 5, 2010.^{[3]} It consists of four copies of 58P5H1V1 continually hassling a glider, leaving debris behind at a period of 1450.

### Rakes

The first clean c/5 diagonal rake was constructed by Matthias Merzenich on September 7, 2010. The rake has a period of 1585 and works by circulating two gliders.

## Wickstretchers

The first c/5 diagonal wickstretcher was found by Matthias Merzenich on January 26, 2011. It consists of a tagalong pulled by two copies of 58P5H1V1 that stretches two tubs.
