Block on cap is a 12-cell still life composed of a cap being stabilized by a block.
Block on cap is the forty-eighth most common still life in Achim Flammenkamp's census, being less common than elevener but more common than trans-loaf with tail.[1] It is also the fifty-eighth most common object on Adam P. Goucher's Catagolue.[2]
All strict still lifes with a population of 23 or fewer cells, all oscillators with 16 or fewer cells, and all spaceships with 35 or fewer cells are known to be glider-constructible. A glider synthesis of this object can be found in the infobox to the right.
