Cell Shifts for Polynars
A polynar is a plane figure formed by joining equal squares
at whole or half edges.
A cell shift is a pair of arrangements of a polyform
that differ in only one cell.
Here I show the shortest possible cell shift for polynars of order 2 and 3,
using as few tiles as possible.
