发明名称 Truncated icosahedral blocks
摘要 The truncated icosahedral blocks are designed to meet one another along their truncation surfaces and thereby imitate an icosahedron's unique ability for three-dimensional intersection with another icosahedron, so that a line segment that defines the base of a pentangular pyramid on one icosahedron also defines the base of a pentangular pyramid on the other icosahedron.
