Achim's p144 is a period 144 oscillator that was found (minus the blocks shown to the right) on a cylinder of width 22 by Achim Flammenkamp in July 1994. Dean Hickerson reduced it to a finite form using figure eights the same day. The neater finite form shown here - replacing the figure eights with blocks - was found by David Bell in August 1994.
