Basis vectors in real and in reciprocal space. a, b Projected basis vectors of k = 3 tilings in the physical and in the perpendicular space \({\mathbf{a}}_j^\parallel\) and \({\mathbf{a}}_j^ \bot\), respectively. c, d Projected reciprocal-space basis vectors in the physical and in the perpendicular space \({\mathbf{q}}_j^\parallel\) and \({\mathbf{q}}_j^ \bot\), respectively
