Hi All,(adsbygoogle = window.adsbygoogle || []).push({});

Using (Mirror + Translation in 2D).

I see that Diamond and Center Rectangular Lattice in 2D has the same Symmetry i.e:

1)Horizontal Mirror Plane

2)Vertical Mirror Plane

3)2-Fold Rotation Axis.

and Diamond has Smaller Area.

Then why we say Center Rectangular has higher Symmetry and we take it as the Standard Cell.

Reference, Edx.org, Course:

Symmetry, Structure and Tensor Properties of Materials, Lecture 7.

Thanks.
