p26 pre-pulsar shuttle

p26 pre-pulsar shuttle 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.

Generation 4 reveals four pre-pulsars (black) being hassled by a 14-generation mechanism (green) and a 12-generation mechanism (red).

Catagolue: here
gollark: I mean, if you're saying "it is 3 hours after noon", you probably *mean* something like "it's a reasonable time to do X". So say that.
gollark: In what context would they say that, though?
gollark: Hmm, yes, it is possible that people will be beelike about this.
gollark: Or invent "standard lateness units" relative to some sort of poll for local day/night cycles.
gollark: So we just need to standardize "quite late", "very late", and "highly late" or something.
