(184−65, 184, 416)-Net over F₄ — Digital

Digital (119, 184, 416)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(184−65, 184, 11798)-Net in Base 4 — Upper bound on s

There is no (119, 184, 11799)-net in base 4, because

1 times m-reduction [i] would yield (119, 183, 11799)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 150 492530 779746 094695 885890 222533 475192 189509 519014 616151 965873 264159 137851 630272 784493 691587 224888 440352 240560 > 4¹⁸³ [i]
