(90−37, 90, 2099)-Net over F₂₇ — Digital

Digital (53, 90, 2099)-net over F₂₇, using

Gilbertâ€“VarÅ¡amov bound [i]

(90−37, 90, 3470996)-Net in Base 27 — Upper bound on s

There is no (53, 90, 3470997)-net in base 27, because

1 times m-reduction [i] would yield (53, 89, 3470997)-net in base 27, but
- the generalized Rao bound for nets shows that 27^mÂ â‰¥ 24 624999 788348 947520 234313 799606 310349 454997 134059 058919 444902 810641 864956 264678 792990 771309 166925 537141 491290 755280 343076 964865 > 27⁸⁹ [i]
