Gilbertâ€“VarÅ¡amov bound [i]

(23, 23+15, 4783270)-Net in Base 27 — Upper bound on s

There is no (23, 38, 4783271)-net in base 27, because

1 times m-reduction [i] would yield (23, 37, 4783271)-net in base 27, but
- the generalized Rao bound for nets shows that 27^mÂ â‰¥ 91297 710178 490258 474828 581765 072096 188224 393901 639339 > 27³⁷ [i]
