(100, 100+55, 353)-Net over F₄ — Digital

Digital (100, 155, 353)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(100, 100+55, 9869)-Net in Base 4 — Upper bound on s

There is no (100, 155, 9870)-net in base 4, because

1 times m-reduction [i] would yield (100, 154, 9870)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 522 323650 827719 167761 583184 938470 394106 587874 415323 640411 998908 309787 854025 464347 080535 647056 > 4¹⁵⁴ [i]
