(103, 103+55, 384)-Net over F₄ — Digital

Digital (103, 158, 384)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(103, 103+55, 11516)-Net in Base 4 — Upper bound on s

There is no (103, 158, 11517)-net in base 4, because

1 times m-reduction [i] would yield (103, 157, 11517)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 33405 299795 217638 737513 144324 635700 151293 966937 714012 411264 489038 003503 691384 551320 870060 168020 > 4¹⁵⁷ [i]
