(204−120, 204, 812)-Net in Base 4 — Upper bound on s

There is no (84, 204, 813)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 661 845938 351848 534909 147458 520620 702350 722780 514892 411475 138312 775126 911113 124826 011822 595961 198060 525458 715428 882155 559824 > 4²⁰⁴ [i]
