(224−59, 224, 1611)-Net over F₄ — Digital

Digital (165, 224, 1611)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(224−59, 224, 165795)-Net in Base 4 — Upper bound on s

There is no (165, 224, 165796)-net in base 4, because

1 times m-reduction [i] would yield (165, 223, 165796)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 181 728299 909733 208739 537364 908417 117253 789984 842012 076910 785415 258966 353005 889434 159596 526384 132249 424494 071354 988160 737141 325346 854952 > 4²²³ [i]
