1# In 2007 Franklin T. Adams-Watters described a CA in which all the action 2# occurs on the edges of a square grid. Each edge can be on or off and has 3# six neighbors, three at each end. An edge is on in the next generation 4# iff exactly two of the edges in its seven edge neighborhood (including 5# the edge itself) are on. 6# 7# The LifeOnTheEdge rule has 3 live states with suitable icons that allow 8# any pattern of edges to be created. 9# 10# This pattern shows a still life, some oscillators, a few spaceships and 11# a couple of puffers. 12# 13x = 53, y = 23, rule = LifeOnTheEdge 1412.2A15.CA17.A$28.BAC17.B$47.A.A$47.CABA$48.BC4$2.A10.A$.3A8.2C14.C3B 15A$B2.B7.BC14.BA2B.C$.B2AC$3.A4$48.B$48.CA$12.2CA16.CA15.CA$11.C2.BA 1613.AB.C15.B$11.C2.BA12.B2.A12.B2ABAC.AC$11.B2AC15.2B15.BAC$12.2B14.B. 17B17.B! 18
