Squash it into a 3x1 flat rectangle (this move entails some straining on the nylon
wires and cannot be performed with the ideal physical model with rigid tiles and
inextensible wires).
turn 180 degrees a single flap and a pair of adjacent tiles into the final shape.
Note:
This configuration can also be constructed starting from
or
within the model with rigid tiles and inextensible wires.
