#Life 1.05 #D Pseudorandom LWSS generator with p46 logic #D A lightweight spaceship stream is emitted representing a #D pseudorandom binary sequence satisfying the recursion #D a[n] = a[n-1] XOR a[n-19]. (By spreading out the pattern, #D the 19 can be changed.) The sequence has period 413385, #D so the gun has period 46*413385 = 19015710. #D Built by Bill Gosper, October 1989 or earlier #D (Header by Dean Hickerson, 4/11/93) #N #P 16 -18 ** ** #P 15 -32 .** *.* *..* .** #P 22 -32 .** .*.* *..* .** #P 16 -45 ** ** #P -40 -94 ** ** #P -57 -102 ..** .*..** ****** ..**** . . . ..**** ****** .*..** ..** #P -65 -102 .** .** *..* .**.* .**.* #P -67 -96 ...**.* ...**.* **.*** *.*.* .**** ..** #P -119 -51 ** ** #P -118 -39 **...** #P -120 -34 **.* *..* .*** #P -113 -34 *.** *..* *** #P -119 -24 ** ** #P -139 -8 ** ** #P -141 -1 ..***...*** .*..*...*..* .*...*.*...* **.*.*.*.*.** **.**...**.** .***.....*** #P -135 10 ...* ..*.* .*...* .***** *.*.*.* .*...* . .*...* *.*.*.* .***** .*...* ..*.* ...* #P -139 19 ** ** #P -105 13 ** ** #P -93 5 .** *..* *..* .*** . . . .*** *..* *..* .** #P -78 13 ** ** #P -72 11 ** ** #P -60 3 .** *..** *...* .*..* .*** . .*** .*..* *...* *..** .** #P -45 11 ** ** #P -120 33 ** ** #P -106 24 ......* .*...* * *..** .** ..*** . ..*** .** *..** * .*...* ......* #P -98 22 .....***...* ...*****..*.* ..**...**...* ..***...*..* .*.**...*** ..* *..**...*** *****...*..* ..**...**...* ********..*.* *..*.***...* ..* .** #P -73 30 ** ** #P -63 27 ** ** #P -55 19 ..** .*.* **.* .** ..* . ..* .** **.* .*.* ..** #P -27 22 .** **.** .*..* .*..* ..** . ..** .*..* .*..* **.** .** #P -16 30 ** **
