(134−45, 134, 382)-Net over F₄ — Digital

Digital (89, 134, 382)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(134−45, 134, 13148)-Net in Base 4 — Upper bound on s

There is no (89, 134, 13149)-net in base 4, because

1 times m-reduction [i] would yield (89, 133, 13149)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 118 709012 115660 895323 808229 961392 195957 997151 707393 468137 979198 032208 668241 305860 > 4¹³³ [i]
