(119, 178, 508)-Net over F₄ — Digital

Digital (119, 178, 508)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(119, 178, 18368)-Net in Base 4 — Upper bound on s

There is no (119, 178, 18369)-net in base 4, because

1 times m-reduction [i] would yield (119, 177, 18369)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 36699 982303 343591 346474 003776 124044 397620 835215 200214 957940 145070 811352 115047 997596 193685 571227 646544 783104 > 4¹⁷⁷ [i]
