Backrake 1 is a period 8 backrake that was discovered by Jason Summers on March 18, 2001.[1] In the form showed in the image, 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 p2 c/2 spaceship.
