(251−72, 251, 75013)-Net in Base 4 — Upper bound on s

There is no (179, 251, 75014)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 13 094834 561966 348426 468670 957102 309744 576383 291115 725658 875442 609021 796154 845746 021788 733528 581274 819841 088731 467431 227083 603993 144669 548877 918018 779896 > 4²⁵¹ [i]
