#D Line Puffer of width 33
|
|
#D
|
|
#D The width is defined by the length of the first free-standing line
|
|
#D in the puffer's plume. The formula for this is 12n+1-s, where n is
|
|
#D the number of middle segments, and s is the number of cells covered
|
|
#D by the little 3-cell, 5-unit puff-suppressors on the upper edge of
|
|
#D this otherwise symmetrical pattern.
|
|
#D
|
|
#D Here, n=4, and s=6+5+5. The Y-shaped puff-suppressors can have 5,
|
|
#D 6, or 7 units of spacing on between them, or between one of them and
|
|
#D the end. You only need 2 or 3 such suppressors to produce any
|
|
#D puffer width.
|
|
#D
|
|
#D Notice that placing random debris behind the puffer sometimes
|
|
#D affects the plume permanently - even turning it asymmetrical if the
|
|
#D debris was asymmetrical. It also affects the period of the puffer,
|
|
#D that is, the number of generations it takes to repeat. By
|
|
#D increasing the width, the period can be made to rise exponentially,
|
|
#D surpassing 10^6 at a width of only about 70. But the most amazing
|
|
#D thing is that it has a half-life on the order of 10^8 generations.
