Abstract:Recently, Hamada et al. (Des. Codes Cryptogr. 2(1992), 225–229) showed that there exists an 87,5,57;3]-code meeting the Grismer bound. But it is unknown whether or not an 87,5,57;3]-code is unique up to equivalence. In order to characterize all 87,5,57;3]-codes, it is sufficient to characterize all {2v2 + 2v3,2v1 + 2v2; 4, 3}-minihypers and in order to characterize all {2v2 + 2v3,2v1 + 2v2;4,3}-minihypers, it is necessary to characterize all {3v1 + v3,3v0 + v2;3,3}-minihypers, where v0 = 0, v1 = 1, v2 = 4 and v3 = 13 (cf. Hamada and Helleseth, J. Statist. Plann. Inference, 56 (1996)). The purpose of this paper is to characterize all {3v1 + v3,3v0 + v2;3,3}-minihypers.
