A p8 swan tagalong was discovered by Jason Summers in November 2000.[1] Pulled by the distant dot sparks from two swans, it was the first known c/4 diagonal spaceship with a period higher than period-4 to be discovered.
While the spaceship overall is glide-symmetric in its evolution, it has a kinetic symmetry of n/ similarly to oscillators like mold, rather than n/e like the glider, as the diagonal line of reflection passes through cell vertices and centers, rather than only edges like that of a n/e spaceship.
