Hebdarole is a period-7 oscillator that was found by Noam Elkies in November 1997. It was originally found in the larger but more symmetric induction coil form shown below that creates 2 sparks. The smaller version shown to the right was found soon after by Alan Hensel using a component found by David Buckingham in June 1977, but that only creates one domino spark.

Its population cycles between 97, 103, 99, 111, 103, 119, and 107 cells.
