#Life 1.05
#D Superstable line puffer of width 76
#D 
#D The slight instability in the previous line
#D puffer is corrected in this version, which
#D is believed to be perfectly stable and not
#D have a half-life.  In the previous version,
#D a line puffer of width 76 collapses after
#D 39.7 million generations.
#D 
#D Unfortunately, adding puff-suppressors
#D brings back the instability.  So the formula
#D for the width of this puffer is 12n+7m+7,
#D introducing 7-unit spacers so that all
#D sufficiently large widths are possible.
