To construct a ( + 2, )-net from MOLS(), represent the MOLS as an orthogonal array, OA( + 2, ) (see above). The ordered pairs of entries in each row of the orthogonal array in the columns labeled and , will be considered to be the coordinates of the 2 points of the net. Each other column (that is, Latin square) will be used to define the lines in a parallel class. The lines determined by the column labeled L"i" will be denoted by "l""ij". The points on "l""ij" will be those with coordinates corresponding to the rows where the entry in the L"i" column is . There are two additional parallel classes, corresponding to the and columns. The lines "j" and "j" consist of the points whose first coordinates are , or second coordinates are respectively. This construction is reversible.
