Carrier bridge table is a 12-cell still life.

Construction

On April 4, 2007, Dean Hickerson found a 4-glider synthesis of this still life.^[1]

Occurrence

Among still lifes with 12 cells, this is the 27th most common still life according to Catagolue.

There are no collisions in octohash, octo3obj or octo3g databases with this still life occurring in the ash.
