Pre-pulsar shuttle 26 is a period-26 pre-pulsar shuttle oscillator discovered by David Buckingham on January 18, 1983 with an alternate stabilization using beehives rather than blinkers.[1] Its original form was the first period-26 oscillator to be found. It is composed of four 14-generation pre-pulsar shuttle mechanisms that use a blinker stabilization found by Noam Elkies on April 22, 1997,[2] as well as a central 12-generation pre-pulsar shuttle mechanism composed of four beacons. On November 17, 2016, Thunk found a smaller 14-generation pre-pulsar shuttle mechanisms, resulting in a 144-cell variant of this oscillator.

The 200-cell variant was the smallest known period-26 oscillator (in terms of minimum population) until the discovery of the p26 glider shuttle in February 2012. The smallest known period-26 oscillator is currently 87P26.
