(94, 147, 319)-Net over F₄ — Digital

Digital (94, 147, 319)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(94, 147, 8431)-Net in Base 4 — Upper bound on s

There is no (94, 147, 8432)-net in base 4, because

1 times m-reduction [i] would yield (94, 146, 8432)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 7980 159820 034793 786097 902960 409181 799300 205651 581554 696448 492857 201634 138464 404537 929970 > 4¹⁴⁶ [i]
