Glider-block cycle

The glider-block cycle is an infinite oscillator based on the following reaction (a variant of the rephaser). The oscillator consists of copies of this reaction displaced 2n spaces from one another (for some n > 6) with blocks added between the copies in order to cause the reaction to occur again halfway through the period. The period of the resulting infinite oscillator is 8n − 20. (Alternatively, in a cylindrical universe of width 2n the oscillator just consists of two gliders and two blocks.)
