#N Back and forth fuse
#C A p1200 oscillator based on a fuse in which a pi heptomino
#C moves at speed 17c/45 along a line of blinkers spaced 17 units
#C apart, shifting the blinkers 6 units in the process.  In this
#C oscillator, p240 guns are used to reverse the pi when it reaches
#C either end of the line.
