DryLife  


Rulestring  23/37 B37/S23 


Character  Exploding 
DryLife is a Lifelike cellular automaton in which cells survive from one generation to the next if they have 2 or 3 neighbours, and are born if they have 3 or 7 neighbours.
Patterns
DryLife is so named because the standard spaceships from normal life; lightweight spaceship, middleweight spaceship, and heavyweight spaceship — also known as "fishes" — do not work, though the glider does. Some other spaceships, such as the weekender and loafer, work in this rule. The copperhead evolves into the closely related c/10 goldenhead, differing from copperhead by two cells in one phase.
Two correctly spaced Bheptominoes (as in the twin bees shuttle) act as a c/2 orthogonal puffer.
A new speed allowed by DryLife is 9c/28 orthogonal. Technology travelling at this speed relies on the Rpentomino. There is a small 9c/28 orthogonal pond puffer, and a 9c/28 spaceship. Guns and breeders have been constructed that fire spaceships and rakes of this speed respectively.
The "flower garden", a common constellation which evolves from honey farm predecessors, composed of two biboats and two cismirrored Rbees, is shown to the right.
Universality
There is a proof sketch of this rule's universality. It is on conwaylife forums^{[1]}, which contains a proofscheme covering all rules that support glider and their rulestring matches B3[678]*/S23[678]*.
