“…Steiner-Routh's theorem which is sometimes called just Routh's theorem was discussed in many papers and books. See [33] p. 166, [14] p. 33, [29] p. 89, [12] p. 41-42, [20], [10] p. 211, 212, [1], [2], [37], [16] p. 382, [17], [23], [8], [7] p. 276, [36], [30], [32], [31], [11], and their references. Steiner-Routh's formula was generalized in many different directions: [6], [9], [19], [18], [40].…”
