ZOO
A Zoo of Life forms, Harold V. McIntosh.
Abstract A catalog is presented, of those Life forms on strips of widths up to six whose translational behaviour during a single generation can be inferred from two stages of de Bruijn diagrams. This paper is available in PDF (zoo.pdf).
Still Lifes
Life's Still Lifes.
Abstract The de Bruijn diagram describing those decompositions of the neighborhoods of a one dimensional cellular automaton which conform to predetermined requirements of periodicity and translational symmetry shows how to construct extended configurations satisfying the same requirements. Similar diagrams, formed by stages, describe higher dimensional automata, although they become more laborious to compute with increasing neighborhood size. The procedure is illustrated by computing some still lifes for Conway's game of Life , a widely known two dimensional cellular automaton.
