(136, 136+77, 437)-Net over F₄ — Digital

Digital (136, 213, 437)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(136, 136+77, 11411)-Net in Base 4 — Upper bound on s

There is no (136, 213, 11412)-net in base 4, because

1 times m-reduction [i] would yield (136, 212, 11412)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 43 330810 336432 562283 024421 386551 720919 800398 054477 907375 312049 894640 071071 285333 423119 378220 271691 427452 836025 458103 413361 561168 > 4²¹² [i]
