(164, 257, 513)-Net over F₄ — Digital

Digital (164, 257, 513)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(164, 257, 13411)-Net in Base 4 — Upper bound on s

There is no (164, 257, 13412)-net in base 4, because

1 times m-reduction [i] would yield (164, 256, 13412)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 13425 334292 807071 210187 281565 601618 139956 801577 902212 010056 421498 197070 555771 891015 101087 605985 429326 897926 926057 942453 108692 683949 839430 582241 746328 494384 > 4²⁵⁶ [i]
