Achim's p144 is a period-144 oscillator that was found (minus all the blocks) on a cylinder of width 22 by Achim Flammenkamp on July 21, 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 on August 8, 1994.
See factory for a use of this oscillator.
