Oblique lattice

Oblique lattice	Wallpaper group p2	Unit cell

The oblique lattice is one of the five two-dimensional Bravais lattice types.^[1] The symmetry category of the lattice is wallpaper group p2. The primitive translation vectors of the oblique lattice form an angle other than 90° and are of unequal lengths.

Crystal classes

The oblique lattice class names, Schönflies notation, Hermann-Mauguin notation, orbifold notation, Coxeter notation, and wallpaper groups are listed in the table below.

Geometric class, point group				Arithmetic class	Wallpaper groups

C₁	1	(1)	[ ]⁺	None	p1 (1)
C₂	2	(22)	[2]⁺	None	p2 (2222)
