Unique symmetric (66, 26, 10) design admitting an automorphism of order 55

we have proved that the first known symmetric (66, 26, 10) design, constructed by Tran van Trung, is up to isomorphism the only symmetric (66, 26, 10) design admitting an automorphism of order 55. A full automorphism group of that design is isomorphic to Frob55xD10.
