Cis-block on candlefrobra was found by either Robert Wainwright in November 1984[1] or Dean Hickerson on September 10, 1989.[2][note 1]

Occurrence

See also: List of common oscillators

Cis-block on candlefrobra is about the forty-seventh most common naturally-occurring oscillator in Achim Flammenkamp's census.[4] On Catagolue, it is the fifth most common period 3 oscillator, being 1.49 times less common than caterer but 4.20 times more common than cis-beehive on candlefrobra. It is 2.88 times rarer than the trans isomer.[5]

Construction

A 6-glider synthesis of the cis-block on candlefrobra was found in November 2020, based on a 5-glider synthesis of the cis-boat down version.[6] A 5-glider synthesis was found in March 2023.[7]

Notes

  1. ↑ This discrepancy appears to be due to a mistake while writing the Life Lexicon. Hickerson does not give this oscillator a name in his collection, and instead uses "candlefrobra" to refer to a variant of candelabra, attributing the latter to Wainwright instead.[3]
