Symmetry operators:

magnetic

q vectors (optional):
q1 = a1* + a2* + a3*
q2 = a1* + a2* + a3*
q3 = a1* + a2* + a3*

New basis vectors of the reciprocal lattice:
a1*' = a1* + a2* + a3*
a2*' = a1* + a2* + a3*
a3*' = a1* + a2* + a3*

New q vectors:
q1' = q1 + q2 + q3 + a1* + a2* + a3*
q2' = q1 + q2 + q3 + a1* + a2* + a3*
q3' = q1 + q2 + q3 + a1* + a2* + a3*

Old superspace origin in new coordinate system (the "s" subscript in asi' indicates superspace rather than external-space basis vectors):
τ = as1' + as2' + as3' + as4' + as5' + as6'
