Klarner's pentacube puzzle
David Klarner gave us as mathematics students a christmas puzzle
when he was visiting professor at Utrecht University.
25 guilders were awarded to the student who wrote a computer program
that could in a reasonable time (25 hours on an X-6 ??) solve the
problem to pack 25 Y-pentacubes in a 5
This puzzle looks easier than it is. I copied the first solution.
Remarkebly there are 236 diffrerent packings.
The objects are made of unglazed baked chamotte clay.
The modulus is 6 mm. So the cube is 3
