B29 is a c/4 diagonal spaceship discovered by Hartmut Holzwart in September 2004. In generation 2 it produces an isolated domino spark that can be used to perturb reactions. In terms of its 29 cells, it is the fourth smallest c/4 diagonal spaceship, as well as the smallest c/4 spaceship to not exhibit glide symmetry. There are three ways in which a glider can non-trivially follow a B29, as shown below.
B29 is one of the few spaceships with a known glider synthesis.
Two gliders can be seen at the front of the ship, one of these being temporary and the other permanent, making this a tagalong. The other glider does not stay as a glider but still moves like one.
