Semidefinite bounds for mixed binary/ternary codes

Bart Litjens

For nonnegative integers $n_{2}, n_{3}$ and $d$ , let $N (n_{2}, n_{3}, d)$ denote the maximum cardinality of a code of length $n_{2} + n_{3}$ , with $n_{2}$ binary coordinates and $n_{3}$ ternary coordi…

Semidefinite bounds for nonbinary codes based on quadruples

Bart Litjens, Sven Polak, Alexander Schrijver

For nonnegative integers $q, n, d$ , let $A_{q} (n, d)$ denote the maximum cardinality of a code of length $n$ over an alphabet $[q]$ with $q$ letters and with minimum distance at least $…
