(142, 142+46, 262113)-Net in Base 4 — Upper bound on s

There is no (142, 188, 262114)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 153914 933536 776801 833238 653538 872844 104760 496510 748536 544463 643943 790699 364495 748515 744256 493796 248409 308985 488592 > 4¹⁸⁸ [i]
