a A view of the quintuple nest, slightly off a twofold axis, and b along a common threefold axis. c Views along the threefold axis of the double 555 and 444 nest, d the double 555 and 333 nest, and e the double 444 and 333 nest. f A view of the quintuple nest along four- and twofold axes. g Views of the double 555 and 444 nest along two- and fourfold axes, h the double 555 and 333 nest along twofold axes, and i the double 444 and 333 nest along four- and twofold axes. The solids are arbitrarily scaled.
