This is the smallest way to stabilize a house. As a house can act as an eater 1 if both sides are used at once, it sometimes gets used in symmetric oscillators despite being asymmetric itself.
All strict still lifes with a population of 22 or fewer cells, all oscillators with 16 or fewer cells, and all spaceships with 31 or fewer cells are known to be glider-constructible. A glider synthesis of this object can be found in the infobox to the right.
