p28 pre-pulsar shuttle

p28 pre-pulsar shuttle is a period-28 pre-pulsar shuttle oscillator. It consists of a pre-pulsar being hassled by two 14-generation shuttle mechanisms.

Discovered by thunk

Year of discovery 2016

David Buckingham discovered the first period-28 pre-pulsar shuttle, newshuttle, in 1973. The variant shown at right was found by thunk on November 17, 2016,[1] and incorporates shuttle mechanisms by David Buckingham (block and eater), Bill Gosper (mold), and thunk (blocks, blinkers, and tubs). In terms of its 53 cells, this oscillator was tied with mold on 41P7.2 and T-nosed p4 on 28P7.4 as the smallest known non-trivial period-28 oscillator until the discovery of mold on 34P14 shuttle in 2018.

Generation 4 reveals that the object being hassled is a pre-pulsar
gollark: Or, well, future GPT-x.
gollark: How long before GPT-3 can make esolangs and obsolete humanity?
gollark: We rationalize things to death instead of thinking rationally, our reasoning is built on tangles of cognitive biases, and humans cannot effectively multitask.
gollark: Why would you design MentalHealthBot™ with a human-like brain? Humans are uncool.
gollark: It's not like this sort of thing would need to be designed along human lines, though.
