"Imaginary Cube 3H=6" (Author: Professor Hideki Tateki, Graduate School of Human and Environmental Studies, Kyoto University) This item was pre-ordered at the Kyoto University Museum. I owned it as an object after learning through the puzzle. From the Kyoto University HP ↓ ↓ ↓ __________________________ This is a puzzle where you put 9 polyhedral pieces into a cube-shaped box. The polyhedra used in this puzzle are two types of imaginary cubes, H and T. H and T have beautiful geometric properties, such as filling three-dimensional space with two types of solids. "I want to convey this fun," is what led to the design of this 3H=6T puzzle. Solving the puzzle is fun, but there's an even more interesting story waiting beyond that. Please enjoy. __________________________ #puzzle #educationaltoy #KyotoUniversity #object
