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.
