186P24 is an unnamed period-24 oscillator that was discovered by Bill Gosper on October 21, 1994. It was the first non-trivial period 24 oscillator to be found, 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.
