Axial settings, indices and lattice parameters

Co vertical distance between two interlayer cations on the opposite sides of an M layer (cq = cicosP ) 

N number of layers in the unit cell of the (pseudo)-orthohexagonal setting N = N for orthogonal polytypes, TV = 3TV for non-orthogonal polytypes T, character ( 0 5 ) indicating the mica OD packet orientation 

2y+i character ( 0 5 ) indicating the displacement between two adjacent mica OD packets p2y and q2j+i 

/-th composite row translationally independent reciprocal lattice row parallel 

symbol identifying the node features of a row of the reciprocal lattice parallel to c. I is the number of reflections in the c i repeafy a sequence number.
