symmetry()

R2 symmetry	(	str	orbifold,
		*	,
		torch.dtype	dtype = ...,
		torch.device	device = ...,
		bool	requires_grad = False )

Return the symmetry operators for a given symmetry group as a batch of rank two tensors

:param orbifold:    String giving the orbifold notation for the symmetry group
:param dtype:       Floating point scalar type used throughout the model.
:param device:      Device on which the model will be evaluated. All parameters, buffers,
    and custom data are synced to the given device.
:param requires_grad: If true, turn on requires_grad in the resulting tensor
