(17, 43, 2053910)-Net in Base 256 — Upper bound on s

There is no (17, 43, 2053911)-net in base 256, because

the generalized Rao bound for nets shows that 256^mÂ â‰¥ 35 836016 932798 992869 423908 186922 614412 082465 846048 950616 810486 519332 078279 738126 514499 656449 835571 476916 > 256⁴³ [i]
