mekso binary operator: left-handed vectorial cross product (ordered input), -a \times b = b \times a (if using right-hand convention - notice the negative sign/operator or order).

This (which could be denoted "-×") is the opposite of the traditional-in-English vectorial cross-product (which is usually denoted "×"). Generally noncommutative; left-handed in three dimensions. See also: za'ei.

_{1}is clockwise/right-turn-direction of[/to] x_{2}along/following track x_{3}[path] in frame of reference x_{4}(where the axis is within the region defined by the track as the boundary, as viewed from and defined by view(er) x_{4}; see notes); x_{1}is locally to the right of x_{2}, according to x_{4}, constrained along x_{3}; x_{1}is along a right turn from x_{2}along path x_{3}, as viewed in frame x_{4}. - za'ei
