(250−142, 250, 585)-Net in Base 3 — Upper bound on s

There is no (108, 250, 586)-net in base 3, because

the generalized Rao bound for nets shows that 3^mÂ â‰¥ 211978 197238 872456 327715 520432 633734 517565 489693 527645 352105 600492 849737 853792 516135 858026 756731 612451 751547 723578 786249 > 3²⁵⁰ [i]
