The Didrafter Fish
In March 2020, puzzle designer Christoph Lohe
asked me how to fit the 13
proper and extended didrafters
compactly on a page.
Didrafters are formed by
joining two 30°-60°-90° right triangles
at their legs, hypotenuses, or half hypotenuses.
On April 1
I sent Chris the fish
(poisson) shown above.
It uses all 13 didrafters, it has no holes, and it fits compactly
in its bounding rectangle.
Later I found that the didrafters will fit into a smaller rectangle
in many ways.
Here is one:
