(230−152, 230, 583)-Net in Base 4 — Upper bound on s

There is no (78, 230, 584)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 3 107050 873179 930897 348282 951046 345045 386947 656273 767184 571779 496758 948610 287659 909277 230475 914533 603848 457874 081870 374801 700887 389070 904256 > 4²³⁰ [i]
