R. Dawson states: "V.

Second in Fairy Chess Review (vol.4 no.3 Dec 1939 p.43 problem 4135, with solution in no.6 Jun 1940 p.93.) he gives a symmetric tour with squares in a knight chain. The editor states: "VO notes that he examined 144 dispositions of the squares, all that are possible for diametral symmetry, and this is the only case leading to a tour. Moreover every move of the tour is determined, so that the tour is UNIQUE in all the millions possible."
