(176, 176+59, 2087)-Net over F₄ — Digital

Digital (176, 235, 2087)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(176, 176+59, 280521)-Net in Base 4 — Upper bound on s

There is no (176, 235, 280522)-net in base 4, because

1 times m-reduction [i] would yield (176, 234, 280522)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 762 221009 786056 576572 762636 308086 361469 546800 011840 865793 453884 720371 801168 995684 570270 549964 258271 245660 803247 438066 042220 992084 578103 932976 > 4²³⁴ [i]
