20P2 is a period 2 oscillator composed of a beacon stabilizing an unnamed induction coil (a weld of a dock and a mango).
20P2 is about the thirty-fourth most common naturally-occurring oscillator in Achim Flammenkamp's census, being slightly less common than the cis-beacon on cap and the 1 beacon but more common than the cis-beacon down on long hook. It is currently the most common unnamed oscillator.
