Listing of the symmetry elements relating to CBED patterns under the classifications of `vertical' (I), `horizontal' (II) and combined or roto-inversionary axes

I. Vertical symmetry elements
International symbols
$[\eqalign{&2, 3, 4, 6 \quad (2_{1}, 3_{1}, \ldots)\cr &m \;\phantom{2, 3, 4, 6} (c)\cr &a, b \!\!\phantom{2, 3, 4, 6} (n)}]$
II. Horizontal symmetry elements
	Diperiodic symbols	BESR symbols
	2′	m
	$[2'_{1}]$
	m′	$[1_{R}]$
	a′, b′, n′
	$[\bar{1}']$	$[2_{R}]$
$[\hbox{I} + \hbox{II}]$	$[\bar{4}']$	$[4_{R}]$
$[\hbox{I} \times \hbox{II}]$	$[\bar{3}' = 3 \times \bar{1}']$	$[6_{R} = 3 \cdot 2_{R}]$
	$[\bar{6}' = 3 \times m']$	$[31_{R}]$
