#Life 1.05 #D Diagonal sawtooth with expansion factor 4 #D Population is unbounded but does not tend to infinity. Its graph #D is a sawtooth function with ever-increasing teeth. #D #D A p960 gun sends gliders southwest. Some are deleted; the others #D reflect off the back of a Cordership. Each returning glider #D deletes 2 outgoing ones. #D #D Note the use of an in-line inverter found by David Bell. #D This was built by David Bell 8/29/92 #D (header written by Dean Hickerson) #N #P 20 -7 ....*.*..*.* **.*..*..*..*.** ....*.*..*.* #P 50 -3 ..*** .*...* *.....* #P 49 1 * * #P 57 1 * * #P 50 4 *.....* .*...* ..*** #P 48 -35 **..** **.*..* ....** #P 57 -37 ** *.* ...* *..* ...* *.* ** #P 68 -35 ....*.* ...*..* ..** **...* ..** ...*..* ....*.* #P 77 -34 ..* ** #P 82 -32 ** ** #P 60 -30 ..* ** .** #P 53 -22 *.* ** .* #P 47 -28 ** *.* * #P 33 -15 **..** **.*..* ....** #P 42 -17 ** *.* ...* *..* ...* *.* ** #P 49 -12 ** #P 53 -15 ....*.* ...*..* ..** **...* ..** ...*..* ....*.* #P 62 -14 ..* ** #P 67 -12 ** ** #P 45 -10 ..* ** .** #P -67 111 ......* . .*.** .*.*......* *....**...* .*........* .*.......* . .....* #P -55 118 ..*** ...**.** ...**.* ...*.* ...*.* ....** ......* ...*.* ..* . . ....*...* *...* ......* .....** . ..**.** ....* #P -41 137 ......* . .*.** .*.*......* *....**...* .*........* .*.......* . .....* #P -28 138 ..*** ..*.* **..* *** *** #P -55 97 .....* ***.*.**** ...**.* .**....**.* #P -45 101 ..* **.*.** ..**.* ....* #P -43 107 .....* ..***.** **.*** ....* . ...* ...* ...* .*.* ..* #P -42 120 ...* ...** ....* .*.* *..* *.* *.* .* #P -35 76 .** ..** ..* ..** .** . ..* *** ...*.* .*...** .....* . .*** #P -22 95 ...* ..*** . *...*....*.* *....**.***** *..*.*..*...* .....* #P -9 102 .** ..** ..* ..** .** . ..* *** ...*.* .*...** .....* . .*** #P -38 74 ** ** #P -46 82 ** ** #P -54 90 ** ** #P -62 98 ** ** #P 0 120 ** ** #P -8 128 ** ** #P -16 136 ** ** #P -84 -144 ..* .** *** .** ..* #P -75 -144 * ** *** ** * #P -73 -151 **...** **...** .***** ..*.* . ..*** #P -71 -160 ** *..* . ....* . ..** .*
