(107, 164, 398)-Net over F₄ — Digital

Digital (107, 164, 398)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(107, 164, 12020)-Net in Base 4 — Upper bound on s

There is no (107, 164, 12021)-net in base 4, because

1 times m-reduction [i] would yield (107, 163, 12021)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 136 977786 158923 130806 836012 043157 184822 435127 103663 525580 876437 466480 627111 436018 054693 567625 377996 > 4¹⁶³ [i]
