Abstract
Two skew Hadamard matrices are considered {\sf SH}-equivalent if they are similar by a signed permutation matrix. This paper determines the number of {\sf SH}-inequivalent skew Hadamard matrices of order for some types. We also study ternary self-dual codes and association schemes constructed from the skew Hadamard matrices of order .
