The name was suggested by Bill Gosper, noting that the {phase} shown below displays the period in binary. ....**......**.... ...*.*......*.*... ...*..........*... **.*..........*.** **.*.*..**..*.*.** ...*.*.*..*.*.*... ...*.*.*..*.*.*... **.*.*..**..*.*.** **.*..........*.** ...*..........*... ...*.*......*.*... ....**......**.... :1-2-3: (p3) Found by Dave Buckingham, August 1972. This is one of only three essentially different p3 {oscillator}s with only three cells in the {rotor}. The others are {stillater} and {cuphook}. ..**...... *..*...... **.*.**... .*.*..*... .*....*.** ..***.*.** .....*.... ....*..... ....**.... :1-2-3-4: (p4) See also {Achim's p4}. .....*..... ....*.*.... ...*.*.*... ...*...*... **.*.*.*.** *.*.....*.* ...*****... ........... .....*..... ....*.*.... .....*..... :14-ner: = {fourteener} :2 eaters: = {two eaters} :4-8-12 diamond: The following {pure glider generator}. ....****.... ............ ..********.. ............ ************ ............ ..********.. ............ ....****.... :4 boats: (p2) ...*.... ..*.*... .*.**... *.*..**. .**..*.* ...**.*. ...*.*.. ....*... :4F: = {Fast Forward Force Field} :Achim's p144: (p144) This was found (minus the blocks shown below) on a cylinder of width 22 by Achim Flammenkamp in July 1994. Dean Hickerson reduced it to a finite form using {figure-8}s the same day. The neater finite form shown here - replacing the figure-8s with blocks - was found by David Bell in August 1994. See {factory} for a use of this oscillator. **........................** **........................** ..................**........ .................*..*....... ..................**........ ..............*............. .............*.*............ ............*...*........... ............*..*............ ............................ ............*..*............ ...........*...*............ ............*.*............. .............*.............. ........**.................. .......*..*................. ........**.................. **........................** **........................** :Achim's p16: (p16) Found by Achim Flammenkamp, July 1994. .......**.... .......*.*... ..*....*.**.. .**.....*.... *..*......... ***.......... ............. ..........*** .........*..* ....*.....**. ..**.*....*.. ...*.*....... ....**.......
