(115, 176, 428)-Net over F₄ — Digital

Digital (115, 176, 428)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(115, 176, 13027)-Net in Base 4 — Upper bound on s

There is no (115, 176, 13028)-net in base 4, because

1 times m-reduction [i] would yield (115, 175, 13028)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 2294 938178 719607 514009 891232 367817 243992 782374 703316 753887 910722 390294 754473 144194 207243 287531 502222 506248 > 4¹⁷⁵ [i]
