(49, 86, 1461)-Net over F₂₇ — Digital

Digital (49, 86, 1461)-net over F₂₇, using

Gilbertâ€“VarÅ¡amov bound [i]

(49, 86, 1668676)-Net in Base 27 — Upper bound on s

There is no (49, 86, 1668677)-net in base 27, because

1 times m-reduction [i] would yield (49, 85, 1668677)-net in base 27, but
- the generalized Rao bound for nets shows that 27^mÂ â‰¥ 46 336512 693236 275551 809773 636212 456729 639192 515016 594467 732908 387734 763127 313224 149704 415834 045280 837495 964390 216061 546465 > 27⁸⁵ [i]
