This is a TT2 dissection that uses a variable decagon strip. The two overlays show the strips before and after the modification of the decagon strip that saves a piece.
I am very pleased with this dissection. It is one of only two dissections in which I use this particular decagon strip.

Discovered by Harry Lindgren (1964).
The two overlay diagrams show the decagon strip before and after modification. The first overlay diagram results in a 14 piece dissection: the fourteenth piece is a tiny piece at the bottom left of the overlay parallelogram. The modification results in a saving of two pieces. Usually such a modification only saves a single piece.
