(131, 195, 19860)-Net in Base 4 — Upper bound on s

There is no (131, 195, 19861)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 2523 669014 299893 535892 054045 202858 072017 408309 643593 522473 440938 782875 262311 665291 614675 167685 573504 254144 518131 564060 > 4¹⁹⁵ [i]
