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. Its original form was the first period 26 oscillator to be found. It is composed of four period-14 pre-pulsar shuttle mechanisms that use a blinker stabilization found by Noam Elkies on April 22, 1997, as well as a central period-12 pre-pulsar shuttle mechanism composed of four beacons. In terms of its 200 cells it is the smallest known non-trivial period 26 oscillator.
