(28, 28+27, 326736)-Net in Base 32 — Upper bound on s
There is no (28, 55, 326737)-net in base 32, because
- 1 times m-reduction [i] would yield (28, 54, 326737)-net in base 32, but
- the generalized Rao bound for nets shows that 32m ≥ 1897 189654 853911 585292 194084 719615 485549 195482 493354 389429 402398 527793 232867 821840 > 3254 [i]
