(84, 84+41, 395)-Net over F₄ — Digital

Digital (84, 125, 395)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(84, 84+41, 14944)-Net in Base 4 — Upper bound on s

There is no (84, 125, 14945)-net in base 4, because

1 times m-reduction [i] would yield (84, 124, 14945)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 452 486657 252547 832126 686391 121729 596324 758539 877494 303585 556076 204260 396664 > 4¹²⁴ [i]
