Examples

“Although Lester must still see⟳ doctors on a semiregular basis for checkups, his health has returned to normal.”

“A space is semiregular iff the regularly open⟳ sets (3D) form⟳ a base⟳ for the topology.[…]Every space X can be embedded in a semiregular space.”

“It will be seen below that this semiregular polyhedron is of importance in its relationship to periodic minimal surfaces serving as a conceptual reference.”

“In a semiregular tessellation, there is an isometry of the plane carrying any vertex to any other vertex.”

“While one of the semiregular polyhedra was mentioned by Plato, their first serious study⟳ is attributed to Archimedes.”

“One that we will consider⟳ here is the semiregular tessellation—a tessellation of two or more regular polygons that are arranged so that the same polygons appear⟳ in the same order⟳ around each vertex point⟳. The tessellation at the left in Figure⟳ 9.38 is a semiregular tessellation because the two figures are a square and a regular octagon. The tessellation at the right in Figure⟳ 9.38 is not a semiregular tessellation because the two figures are a square and a nonregular octagon.[…]There are only eight possible semiregular tessellations.”
