Similarly, a k-isohedral tiling has k separate symmetry orbits (it may contain m different face shapes, for m = k, or only for some m < k). [ 6 ] ("1-isohedral" is the same as "isohedral".) A monohedral polyhedron or monohedral tiling ( m = 1) has congruent faces, either directly or reflectively, which occur in one or more symmetry positions.

This shape is called a plesiohedron. The tiling generated in this way is isohedral, meaning that it not only has a single prototile ("monohedral") but also that any copy of this tile can be taken to any other copy by a symmetry of the tiling. [1] As with any space-filling polyhedron, the Dehn invariant of a plesiohedron is necessarily zero. [3]

A Rechtsstaat is a constitutional state in which the exercise of governmental power is constrained by the law. [1] It is closely related to " constitutionalism " which is often tied to the Anglo-American concept of the rule of law , but differs from it in also emphasizing what is just (i.e., a concept of moral rightness based on ethics ...

All four tilings are 2-isohedral. The chiral pairs of tiles are colored in yellow and green for one isohedral set, and two shades of blue for the other set. The pgg symmetry is reduced to p2 when the chiral pairs are considered distinct. The tiling by type 9 tiles is edge-to-edge, but the others are not. Each primitive unit contains eight tiles.
The independent state legislature theory or independent state legislature doctrine (ISL) is a judicially rejected legal theory that posits that the Constitution of the United States delegates authority to regulate federal elections within a state to that state's elected lawmakers without any checks and balances from state constitutions, state courts, governors, ballot initiatives, or other ...
