#C A versatile period 26 oscillator.
#C This oscillator occurs spontaneously and is also easily constructed
#C (for example, by a big glider running into the side of a line).
#C The oscillator is able to turn gliders by 90 degrees and reflect
#C gliders back onto their original path.  It is also able to turn  gliders
#C by 90 degrees while changing its own phase to an effective period of 37.
#C This allows glider loops to be constructed having any period of the
#C form 26M+37N.
