(145−89, 145, 2835)-Net in Base 9 — Upper bound on s

There is no (56, 145, 2836)-net in base 9, because

1 times m-reduction [i] would yield (56, 144, 2836)-net in base 9, but
- the generalized Rao bound for nets shows that 9^mÂ â‰¥ 257633 991201 048644 559339 562155 169429 632909 534416 054183 529380 857390 194452 435838 295198 527563 440583 352840 975744 289624 760218 635303 628072 283265 > 9¹⁴⁴ [i]
