Using Grant-in-Aid for Scientific Research of the Ministxy of Education under Contract Number 304-5009-09640286, we have the following results. 1. In the first paper [1] (cf. 11. References) by N.Hamada and M.van Eupen, it has been shown that there do not exist ternary [38, 6, 23] codes and ternary [39, 6, 24] codes and that n_3 (6, 23) = 39, d_3 (38, 6) = 22, n_3 (6, 24) = 40 and d_3 (39, 6) = 23. 2. In the second paper [2] by N.Hamada, it has been shown that there do not exist quaternaiy [293, 5, 219] codes, quaternary [289, 5, 216] codes and quaternary [277, 5, 207] codes and that n_4 (5, 219) = 294, n_4 (5, 216) = 290 and n_4 (5, 207) = 278. 3. In the third paper [3] by N.Harnada and Y.Watamori, it has been shown that there do not exist ternary [79, 6, 51] codes and that n_3 (6, 51) = 80. 4. In the fourth paper [4] by N.Hamada, it has been shown that there do not exist ternary [231, 6, 153] codes and ternary [204, 6, 135] codes and that n_3 (6, 153) 232 and n_3 (6, 135) = 205 or 206. 5. In the fifth paper [5] by N.Hamada, it has been shown that there do not exist quaternary [240, 5, 179] codes, quaternary [243, 5, 181] codes, quaternaiy [244, 5, 182] codes and quaternary [248, 5, 185] codes and that n_4 (5, 179) 241, n_4 (5, 181) = 244, n_4 (5, 182) 245 and n_4 (5, 185) = 249.
