[next configuration]
― Configuration code: RRUmDmLLUmDm
- Start from
- Lower the top four tiles to the left: this is achieved by turning 90 degress
to the left the two vertical tiles
- The resulting flat shape has a row of three stacks of two tiles and a lower row
of two tiles
- Call second floor the set of three tiles on top of the three stacks and
first floor the set of the remaining five tiles
- The two tiles of the first floor on the left of the top row can be lowered 180 degrees
about their lower side
- Of these two tiles, the one on the right can be further turned down 180 degrees to the left
- We have now a flat 2x3 rectangular shape with two stacks of two tiles in opposite corners
- Open it in the final shape
Remark: This configuration is chiral, you can obtain its enantiomorph by following the
above instructions in a mirror.
