New cubic self-dual codes of length 54, 60 and 66. (arXiv:1706.07631v1 [math.NT])
来源于:arXiv
We study the construction of quasi-cyclic self-dual codes, especially of
binary cubic ones. We consider the binary quasi-cyclic codes of length 3\ell
with the algebraic approach of [9]. In particular, we improve the previous
results by constructing 1 new binary [54, 27, 10], 6 new [60, 30, 12] and 50
new [66, 33, 12] cubic self-dual codes. We conjecture that there exist no more
binary cubic self-dual codes with length 54, 60 and 66. 查看全文>>
