- It is well known that if 3 congruent solid cylinders with mutually orthogonal
- axes are intersected in 3-space, the result has 12 curved faces
- arranged like a rhombic dodecahedron.
-
- QUESTION: What is the intersection of 4 congruent solid cylinders
- in 3-space whose axes are the major diagonals of a cube?
