Digital (99, 148, 437)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(148−49, 148, 15897)-Net in Base 4 — Upper bound on s

There is no (99, 148, 15898)-net in base 4, because

1 times m-reduction [i] would yield (99, 147, 15898)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 31856 277067 248357 240047 534586 615774 145874 007422 482761 046303 101194 871053 956045 211227 571161 > 4¹⁴⁷ [i]
