**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 period-24 oscillator, boring p24, can be constructed from two sparkers (pulsar and figure eight) both of which were known by 1970. However, this type of oscillator is generally considered "boring", and thus not counted despite technically being non-trivial.
