We prove the nonexistence of binary [69,9,32] codes and construct codes wit
h parameters [76,9,34],[297,9,146], and [300,9,148]. These results show tha
t n(9,32) = 70, n(9,34) less than or equal to 76,n(9,146) = 297, and n(9,14
8) = 300, where n(k, d) denotes the smallest value of n for which there exi
sts an [n, k, d] binary code. We also present some codes of minimum distanc
e 32 and some related codes.
