(194−112, 194, 836)-Net in Base 4 — Upper bound on s

There is no (82, 194, 837)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 661 530421 684726 319075 426733 272509 498461 258175 369097 316710 631792 431258 458954 073680 135127 358852 491230 995549 167062 945960 > 4¹⁹⁴ [i]
