#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. #D #D Tim Coe, May 1996. #N #P 10 -76 *.* *..* ...** .....* ...**** ..*....* ....*..* ....*..* ......* *.**** *...* ...* .*.* . ..*** ...** ..*** . .*.* ...* *...* *.**** ......* ....*..* ....*..* ..*....* ...**** .....* ...** *..* *.* #P 7 -44 **.* ...* *.** * #P 29 -49 *.* *..* ...** .....* ...**** ..*....* ....*..* ....*..* ......* *.**** *...* ...* .*.* . ..*** ...** ...** ***** ..* ....* ..*.* .....* ..*.* ....* ..* ***** ...** ...** ..*** . .*.* ...* *...* *.**** ......* ....*..* ....*..* ..*....* ...**** .....* ...** *..* *.* #P 15 -33 ...*.*....*.* **.*..*..*..* ......**...* ...*......* ...*.***** ** ...*.***** ...*......* ......**...* **.*..*..*..* ...*.*....*.* #P 23 -78 * **** ..** .....* ..**** ......* ..*..*** ....*** .....* *.*** **..* .*** .* ...* .*.* ....* .*.* ...* .* .*** **..* *.*** .....* ....*** ..*..*** ......* ..**** .....* ..** **** * #P 18 -47 ...*.* ...* .*..** ..*** *.* * * #P 8 -41 .........* .....*.*** ....*.** ....** *..** *.** #P 29 -3 *.* *..* ...** .....* ...**** ..*....* ....*..* ....*..* ......* *.**** *...* ...* .*.* . ..*** ...** ...** ***** ..* ....* ..*.* .....* ..*.* ....* ..* ***** ...** ...** ..*** . .*.* ...* *...* *.**** ......* ....*..* ....*..* ..*....* ...**** .....* ...** *..* *.* #P 15 13 ...*.*....*.* **.*..*..*..* ......**...* ...*......* ...*.***** ** ...*.***** ...*......* ......**...* **.*..*..*..* ...*.*....*.* #P 23 47 * **** ..** .....* ..**** ......* ..*..*** ....*** .....* *.*** **..* .*** .* ...* .*.* ....* .*.* ...* .* .*** **..* *.*** .....* ....*** ..*..*** ......* ..**** .....* ..** **** * #P 10 45 *.* *..* ...** .....* ...**** ..*....* ....*..* ....*..* ......* *.**** *...* ...* .*.* . ..*** ...** ..*** . .*.* ...* *...* *.**** ......* ....*..* ....*..* ..*....* ...**** .....* ...** *..* *.* #P 7 40 * *.** ...* **.* #P 18 40 * * *.* ..*** .*..** ...* ...*.* #P 8 35 *.** *..** ....** ....*.** .....*.*** .........* #P 5 -40 * .* .* .* .* .* .* .* .* .* .* .* .* .* .* .* .* .* .* .* .* .* .* .* .* .* .* .* .* .* .* .* .* .* .* .* .* .* .* .* .* .* .* .* #P 8 -34 *.** *..** ....** ....** *..** *.** . *.** *..** ....** ....** *..** *.** . *.** *..** ....** *..*.** *.***..* .......* *.***..* *..*.** ....** *..** *.** . *.** *..** ....** *..*.** *.***..* .......* *.***..* *..*.** ....** *..** *.** #P 5 4 .* .* .* .* .* .* .* .* .* .* .* .* .* .* .* .* .* .* .* .* .* .* .* .* .* .* .* .* .* .* .* .* .* .* .* * #P 8 4 *.** *..** ....** *..*.** *.***..* .......* *.***..* *..*.** ....** *..** *.** . *.** *..** ....** ....** *..** *.** . *.** *..** ....** *..*.** *.***..* .......* *.***..* *..*.** ....** *..** *.**
