(17, 47, 885200)-Net in Base 256 — Upper bound on s

There is no (17, 47, 885201)-net in base 256, because

the generalized Rao bound for nets shows that 256^mÂ â‰¥ 153915 898121 251920 067152 832242 397291 316675 637353 825740 810555 736786 937467 072551 456810 371714 684966 060923 039295 334576 > 256⁴⁷ [i]
