Reflection conditions for the plane groups

Type of reflections	Reflection condition	Centring type of plane cell; or glide line with glide vector	Coordinate system to which condition applies
hk	None	Primitive p	All systems
		Centred c	Rectangular
		Hexagonally centred h^†	Hexagonal
h0		Glide line g normal to b axis; glide vector $[{1 \over 2}{\bf a}]$	$[\left.\matrix{\noalign{\vskip 54pt}}\right\}\matrix{\hbox{Rectangular, }\hfill\cr\quad\hbox{Square}\hfill}]$
0k		Glide line g normal to a axis; glide vector $[{1 \over 2}{\bf b}]$
