186P24 is an unnamed period-24 oscillator that was discovered by Bill Gosper on October 21, 1994.[1] It was the first non-trivial period 24 oscillator to be found,[note 1] although its original form used t-nosed p4s instead of monograms.
It uses two slightly modified carnival shuttles to make a toad flip its orientation every 12 generations.

Notes
- ↑ A nontrivial period-24 oscillator, such as boring p24, could have been constructed from two oscillators of lower period (such as p3 and p8), both of which were known by an earlier date. However, no such LCM oscillators were attested prior to the discovery of this oscillator in 1994.
