Block on table is a 10-bit still life.
Block on table is the thirty-fourth most common still life in Achim Flammenkamp's census, being less common than moose antlers but more common than block on dock.[1] It is also the forty-fourth most common object on Adam P. Goucher's Catagolue.[2]
It is the most common still life where a block stabilizes an unstable pattern, being barely ahead of the block on dock.
Noah's ark produces blocks on tables along with many common objects.
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.
