Twin hat (or twin peaks, or bi-hat) is a 17-cell still life that roughly consists of two hats.

Commonness

Twin hat is the thirty-sixth most common still life in Achim Flammenkamp's census, being less common than block on dock but more common than beehive on dock; [1] it is the most common object in this census for which no four-glider synthesis is known. The twin hat is also the fourty-eighth most common object on Adam P. Goucher's Catagolue.[2]
