#D The rule is caled "Just Friends" because new cells are born from a pair
#D of parents, but not from ones which are "too intimate" with each other. 
#D A cell stays alive only if it has 1 or 2 live neighbors (in any position).
#D A cell is born only if it has exactly two live neighbors which are not
#D adjacent vertically or horizontally.
#D 
#D So in the following figure, the central cell is born if there are live
#D cells at any two cells marked ac, ad, ae, af, ag, bd, be, bf, bg, bh,
#D ce, cf, cg, ch, df, dg, dh, eg, eh, or fh.

#D The rule has two small period 6 diagonal gliders, an interesting period
#D 236 cyclic oscillator, and a small c/3 orthogonal wickstretcher which
#D show up from random soups.  Lines of cells are stable.  Random soups tend
#D to quickly settle down into small clumps of lines.  But there are lots of
#D spaceships, wickstretchers, rakes, and glider guns which have been built.
#D 
#D Here is a glider loop whose period is not a multiple of the turning
#D oscillator's period! (Is this the first such reaction known in any
#D Life-like rule?)  Here are four gliders circulating with period 408.
