Laves graph
In geometry and crystallography, the Laves graph is an infinite cubic symmetric graph. It can be embedded into three-dimensional space, with integer coordinates, to form a structure with chiral symmetry〔.〕 in which the three edges at each vertex form 120° angles to each other. It can also be defined more abstractly as a covering graph of the complete graph on four vertices.〔〔 named this graph after Fritz Laves, who first wrote about it as a crystal structure in 1932.〔.〕〔.〕 It has also been called the ''K''4 crystal,〔 (10,3)-a network,〔.〕〔.〕 diamond twin,〔 triamond,〔.〕〔.〕 and the srs net.〔.〕 ==Constructions==
