6 bits is the smallest known non-LCM period-75 oscillator. It is a glider shuttle using three pentadecathlons as reflectors. It was found by Robert Wainwright in September 1984.[1]
Moving the lower right pentadecathlon back allows the oscillator to have any period of the form 75+120n.
The name "6 bits" has two meanings. Each pentadecathlon reflects the glider with two "bits" or on cells, totaling six. In addition, dollars used to be divided into 8 bits, so 6 would be 75 cents, and the oscillator is period 75.
