Swan is a c/4 diagonal spaceship producing some useful sparks. It was found by Tim Coe in February 1996. On February 20, 1996 Noam Elkies noticed that it could be made into a small boatstretcher.[1] It can also be combined non-trivially with a Canada goose. In November 2000 Jason Summers found a period-8 glide-reflective tagalong for two swans.[2] This was the first c/4 diagonal spaceship with a period other than period-4 to be found.
