(184−47, 184, 1559)-Net over F₄ — Digital

Digital (137, 184, 1559)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(184−47, 184, 193908)-Net in Base 4 — Upper bound on s

There is no (137, 184, 193909)-net in base 4, because

1 times m-reduction [i] would yield (137, 183, 193909)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 150 317364 233929 197347 059417 898064 713735 001505 145087 913003 393697 829336 324864 099805 909020 436408 550525 599362 136928 > 4¹⁸³ [i]
