38P11.1 is an unnamed period-11 oscillator. Discovered by David Buckingham on June 20, 1977,^[1] it was the first oscillator of this period to be found and was the smallest known until it was surpassed by rattlesnake in 2016. It uses two blocks as induction coils.

A four-fold version of this oscillator appeared semi-naturally in August 2016.^[2]
