(102−35, 102, 284)-Net over F₄ — Digital

Digital (67, 102, 284)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(102−35, 102, 9018)-Net in Base 4 — Upper bound on s

There is no (67, 102, 9019)-net in base 4, because

1 times m-reduction [i] would yield (67, 101, 9019)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 6 439586 597346 716800 379471 262154 638793 205829 733145 135364 216130 > 4¹⁰¹ [i]
