(129, 129+75, 396)-Net over F₄ — Digital

Digital (129, 204, 396)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(129, 129+75, 9786)-Net in Base 4 — Upper bound on s

There is no (129, 204, 9787)-net in base 4, because

1 times m-reduction [i] would yield (129, 203, 9787)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 165 368073 515096 690154 528229 785611 613201 482307 544692 980915 690597 337623 547567 898094 643798 757449 118502 681127 237912 498871 422460 > 4²⁰³ [i]
