Hexagonal lattice — The hexagonal lattice or equilateral triangular lattice is one of the five 2D lattice types.Three nearby points form an equilateral triangle. In images four orientations of such a triangle are by far the most common. They can conveniently be… … Wikipedia
Symmetry combinations — This article discusses various symmetry combinations.In 2D, mirror image symmetry in combination with n fold rotational symmetry, with the center of rotational symmetry on the line of symmetry, implies mirror image symmetry with respect to lines… … Wikipedia
Hexagonal tiling — In geometry, the hexagonal tiling is a regular tiling of the Euclidean plane. It has Schläfli symbol of {6,3} or t{3,6} (as a truncated triangular tiling).Conway calls it a hextille.The internal angle of the hexagon is 120 degrees so three… … Wikipedia
Hexagonal crystal system — In crystallography, the hexagonal is one of the 7 crystal system, it contains 7 point groups . It has the same symmetry as a right prism with a hexagonal base. There is only one hexagonal Bravais lattice, which has six atoms per unit… … Wikipedia
