Block on table is a 10-bit still life.

Occurrence

See also: List of common still lifes, Most common objects on Catagolue

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 the 37th most common still life on Adam P. Goucher's Catagolue, being less common than moose antlers but more common than block on dock. It is the 3rd most common still life with 10 cells, being less common than very long ship but more common than beehive with tail.[2]

It is the most common still life where a block stabilizes an unstable pattern, being 10% more common than the block on dock.

Noah's ark produces blocks on tables along with many common objects.

Glider synthesis

Main article: Glider synthesis

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.
