(92, 139, 383)-Net over F₄ — Digital

Digital (92, 139, 383)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(92, 139, 12854)-Net in Base 4 — Upper bound on s

There is no (92, 139, 12855)-net in base 4, because

1 times m-reduction [i] would yield (92, 138, 12855)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 121461 407916 427905 300205 107404 093988 317826 878859 869023 958446 981868 378570 124639 131236 > 4¹³⁸ [i]
