Sesquihat is a 13-cell still life that is roughly halfway between a hat and twin hat. It is part of an infinite family of stringed beehive halves sandwiched between tails. Odd members have 180 degree rotational symmetry whilst even members have reflective symmetry, both with respect to their midpoints.
Commonness
Sesquihat is the 52nd most common 13-cell still life out of 240.
Glider synthesis
All strict still lifes with a population of 21 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.
