Hooknudger (or pre-block dragger) is a period-4 c/2 orthogonal spaceship. It consists of a hook (pre-pre-block) escorted by three lightweight spaceships. The lightweight spaceships can be substituted by middleweight spaceships or heavyweight spaceships, so that there are 36 different single-hook hooknudgers, all of which have been synthesized.
They functionally resemble the hivenudgers, a class of spaceships which similarly escort a pre-beehive, as well as the comma-pushers, which escort an unnamed, comma-like object.
Further hooknudger variants can be created by replacing either back spaceship with a sidecar, a Coe ship, a hammerhead, a Pushalong 1, a hivenudger or anything else that applies.
