Boat tie spark coil is a period-2 oscillator.


Boat on spark coil is about the thirty-sixth most common naturally-occurring oscillator in Achim Flammenkamp's census, being slightly less common than the cis-beacon down on long bookend, approximately as common as the block on griddle, and more common than fore and back and xp2_8e1t2gozw23.[1] It is the 45th most common oscillator on Adam P. Goucher's Catagolue.

Like a spark coil, this object typically forms when two houses forming from pi heptominoes touch each other in the same generation. A house with a boat attached to a corner is more frequent than random chance would dictate, and it is the same object that mango with block on dock forms from.

Glider synthesis

All strict still lifes with a population of 20 or fewer cells, as well as all oscillators and spaceships with 16 or fewer cells, are known to be glider-constructible. A glider synthesis of this object can be found in the infobox to the right.
