There exists no self-dual [24,12,10] code over F5
Masaaki Harada, Akihiro Munemasa
Self-dual codes over F5 exist for all even lengths. The smallest length for which the largest minimum weight among self-dual codes has not been determined is 24, and the largest mi…
Pseudocyclic association schemes and strongly regular graphs
Akihiro Munemasa, Takuya Ikuta
Let X be a pseudocyclic association scheme in which all the nontrivial relations are strongly regular graphs with the same eigenvalues. We prove that the principal part of the firs…
Mass formula for self-orthogonal codes over Z_{p^2}
Rowena A. L. Betty, Akihiro Munemasa
In this note, we establish a mass formula for self-orthogonal codes over Z_{p^2}, where p is a prime. As a consequence, an alternative proof of the known mass formulas for self-dua…
A Complete Classification of Ternary Self-Dual Codes of Length 24
Masaaki Harada, Akihiro Munemasa
Ternary self-dual codes have been classified for lengths up to 20. At length 24, a classification of only extremal self-dual codes is known. In this paper, we give a complete class…
