Backrake 1 is a period 8 backrake that was discovered by Jason Summers on March 18, 2001.[1] In the form showed in the infobox, it emits a stream of gliders. It can be modified in several ways:
- If the HWSS at the back is removed, it will become a puffer/rake creating nine blocks, eight beehives, six blinkers, two ships and two gliders every 224 generations.
- If the small pattern on the bottommost left side is mirrored onto the right, it will become a puffer creating 14 blocks, ten blinkers, four beehives, two boats, two loaves and two bakeries every 80 generations.
- If the one on the right is mirrored onto the left, it becomes a period 2 c/2 spaceship.
