Candlefrobra (or cis-block and long hook eating tub) was found by either Robert Wainwright in November 1984[1] or Dean Hickerson on September 10, 1989.[2][note 1]

A 6-glider synthesis of the canonical Candlefrobra was found in November 2020, based on a 5-glider synthesis of the cis-boat version.[4]

Commonness

Candlefrobra is about the forty-seventh most common naturally-occurring oscillator in Achim Flammenkamp's census.[5] On Catagolue, it is the fifth most common period 3 oscillator, being less common than caterer but more common than candlefrobra on cis-beehive.[6]

A candlefrobra-on-beacon occurred naturally in May 2015, becoming the first trivial oscillator to occur naturally, as the two rotors do not interact.[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]
