Costas array array. The number of Welch–Costas arrays which exist for a given size depends on the totient function. The Lempel–Golomb construction takes α and β to be primitive elements of the finite field GF("q") and similarly defines formula_1 if formula_4, otherwise 0. The result is a Costas array of size "q" − 2. If "α" + "β" = 1 then the first row and column may be deleted to form another Costas array of size "q" − 3: such a pair of primitive elements exists for every prime power "q>2".
