Donald L Kreher, Stanislaw P Radziszowski
1986 Journal of combinatorial theory. Series A  
A cyclic S- ( 13, 6, 4) design is constructed and is extended to a simple 6-( 14, 7,4) design via a theorem of Alltop. This design is the smallest possible nontrivial simple 6-design that can exist.  ...  The 6 - 6 ( 14, 7, 4) design is constructed via Theorem C of Alltop [ 11.  ...  Proof Let (X, g) be a 6-( 14, 7, 4) design and let G = Aut(&?) be its full automorphism group.
