(23, 23+45, 186396)-Net in Base 128 — Upper bound on s

There is no (23, 68, 186397)-net in base 128, because

1 times m-reduction [i] would yield (23, 67, 186397)-net in base 128, but
- the generalized Rao bound for nets shows that 128^mÂ â‰¥ 1524 468814 816641 257960 895455 922912 230705 923101 703985 673287 158809 901942 243026 746803 677988 528954 300625 041354 672773 359204 693241 275559 379681 110436 > 128⁶⁷ [i]
