B3678/S23 is a Life-like cellular automaton with rulestring B3678/S23. Viewed as the set of neighbour-counting conditions for birth and survival, the rule definition may be seen as the union of HighLife (B36/S23), DryLife (B37/S23) and Pedestrian Life (B38/S23).

Its black/white reversal was called InverseLife by Jason Rampe, whereas the black/white reversal of Life (B3/S23) is called AntiLife (B0123478/S01234678).

Known spaceship speeds in B3678/S23 include[1][2] c/4 diagonal and orthogonal speeds c/2, c/3, c/4, c/5, 2c/5, 2c/8, 3c/8 and 3c/9. Notably, these include the glider and turtle from Life and 27P3H1V0 from HighLife.[3]
