18: B2en3-jq4jknrwz5ace6a/S1c2-n3-ai4ceqy5ai6i7c8 (Whirlwind)

A rule that generally decays to several small oscillators.

Still lives: There is one infinite family known: the aircraft carrier siamesed to itself.

Oscillators: This rule contains three related period-2's: the blinker, the "big blinker" (4 cells in a row) and 2x2's p2 (note that it does not contain the other Margolous oscillators). It also contains a period-4 reminiscent of the beacon, a period-3 star-shaped oscillator and a period-8 that fits the definition of a reflectorless rotating oscillator although not really considered one.

Spaceships: One c/2 orthogonal spaceship and one c/4 diagonal with a domino spark resembling tlife's ant.
