(183, 246, 1984)-Net over F₄ — Digital

Digital (183, 246, 1984)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(183, 246, 237181)-Net in Base 4 — Upper bound on s

There is no (183, 246, 237182)-net in base 4, because

1 times m-reduction [i] would yield (183, 245, 237182)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 3196 748845 112604 023931 529530 876507 969678 805722 445838 606217 231332 670399 650959 306620 687163 923805 650966 320676 723287 465569 503455 859006 973486 223904 035680 > 4²⁴⁵ [i]
