These patterns include snowflake, Penrose, Laves and Altair tilings. Their dual tilings are called Laves tilings in honor of crystallographer Fritz Laves. Ar(H) crystallises in the hexagonal C14 MgZn Laves phase. The tiles of the Laves tilings are called planigons. This construction justifies one of the alternative names of the Laves graph, the "K" crystal. Solid argon hydride (Ar(H)) has the same crystal structure as the MgZn Laves phase. These dual tilings are also called Laves tilings. However, little practical knowledge has been elucidated from Laves phase study so far. Laves lattices are the duals to the Archimedean lattices. Solid argon-hydrogen clathrate (Ar(H)) has the same crystal structure as the MgZn Laves phase. This particular line was christened by Laves in 1941. Between 1816 and 1844, the architect Georg Ludwig Friedrich Laves fully re-built the palace. In geometry and crystallography, the Laves graph is an infinite cubic symmetric graph.
