Symmetry groups of real, bounded, three-dimensional objects are described mathematically by the three-dimensional point groups. The beaded beads in this collection are representations of the icosahedral group (top), the tetrahedral group (middle), and the cube-octahedral group (bottom). Most of these beaded beads are hollow, held open by tension. The objects were constructed with bead weaving, which is a rapidly developing art form and provides a new medium that is rich for discovering and displaying physical representations of these and other symmetry groups.
