(104−47, 104, 1215)-Net over F₂₇ — Digital

Digital (57, 104, 1215)-net over F₂₇, using

Gilbertâ€“VarÅ¡amov bound [i]

(104−47, 104, 932175)-Net in Base 27 — Upper bound on s

There is no (57, 104, 932176)-net in base 27, because

1 times m-reduction [i] would yield (57, 103, 932176)-net in base 27, but
