(155, 232, 636)-Net over F₄ — Digital

Digital (155, 232, 636)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(155, 232, 22855)-Net in Base 4 — Upper bound on s

There is no (155, 232, 22856)-net in base 4, because

1 times m-reduction [i] would yield (155, 231, 22856)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 11 928139 344963 965269 018782 683560 369340 583259 426385 539241 646737 238811 830889 685064 361171 423610 231336 274538 592595 759303 720326 310024 148826 943490 > 4²³¹ [i]
