Properties of the weight distribution of low-dimensional generalized Reed-M
uller codes are used to obtain restrictions on the weight distribution of l
inear codes over arbitrary fields. These restrictions are used in non-exist
ence proofs for ternary linear code with parameters [74, 10, 44] [82, 6, 53
] and [96, 6, 62]. (C) 2001 Elsevier Science B.V. All rights reserved.
