The rule for the composition of collinear velocities in special relativity was stated by Hannon to be mathematically invalid because, in his view, it “violates the transitive law of algebra.” If the rule were invalid, the special theory would be refuted. He did not state by which relation “transitivity” was defined nor why intransitivity implies invalidity.
Keywords: composition of velocities, special relativity, transitivity
