(195, 230, 13435)-Net over F₃ — Digital

Digital (195, 230, 13435)-net over F₃, using

embedding of OOA with Gilbertâ€“VarÅ¡amov bound [i] based on linear OA(3²³⁰, 13435, F₃, 35) (dual of [13435, 13205, 36]-code), using
- discarding factors / shortening the dual code based on linear OA(3²³⁰, 19707, F₃, 35) (dual of [19707, 19477, 36]-code), using

(195, 230, large)-Net in Base 3 — Upper bound on s

There is no (195, 230, large)-net in base 3, because

33 times m-reduction [i] would yield (195, 197, large)-net in base 3, but
- mutually orthogonal hypercube bound [i]
