We construct non-equivalent 476 Hadamard matrices with Hall sets of order 28 containing 13 matrices in papers of \textit{V. Tonchev} [J. Comb. Theory, Ser. A 35, 43-57 (1983; Zbl 0521.05019); 40,42-81 (1985; Zbl 0573.05012)]. In this paper only 20 matrices are listed. Other four examples are in the paper of the first author in J. Comb. Theory, Ser. A 43, 98-102 (1986; Zbl 0598.05017).
