octagrammic prism造句

• The pictures below show the excavation of the octagrammic prism with crossed square cupolae taking place one step at a time.
• The crossed square cupolae are always red, while the square sides of the octagrammic prism are in the other colours.
• To this may be added the great rhombihexahedron, as the exclusive or of all three of these octagrammic prisms which may be used to construct the nonconvex great rhombicuboctahedron.
• Additionally, the nonconvex great rhombicuboctahedron may be seen as an octagrammic prism with the octagrams excavated with crossed square cupolae, similarly to how the rhombicuboctahedron may be seen as an octagonal prism with the octagons augmented with square cupolae.
