(141, 141+64, 30643)-Net in Base 4 — Upper bound on s

There is no (141, 205, 30644)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 2646 189071 993125 262730 849664 442940 437255 868591 424279 690968 833431 450367 270883 894069 711076 846211 113982 348170 938016 821060 464155 > 4²⁰⁵ [i]
