Roteightor is a period 8 oscillator with 35 cells. It was discovered by Robert Wainwright in 1972. It consists of four eater 1s hassling a fleet predecessor that resembles a standard spaceship of length 3, sometimes called an underweight spaceship. It can also be extended as an agar.
The roteightor is period eight, the rotor appears to rotate, and in an extended roteightor with the underweight spaceships in their dense phases the UWSSs that touch resemble black eights.
