(101, 152, 425)-Net over F₄ — Digital

Digital (101, 152, 425)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(101, 152, 14667)-Net in Base 4 — Upper bound on s

There is no (101, 152, 14668)-net in base 4, because

1 times m-reduction [i] would yield (101, 151, 14668)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 8 160009 607216 394081 334603 181868 526635 365597 984516 423045 344723 697812 758266 530395 364934 589332 > 4¹⁵¹ [i]
