(231−74, 231, 27998)-Net in Base 4 — Upper bound on s

There is no (157, 231, 27999)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 11 923802 252805 631465 716076 090749 981318 440343 398878 213908 904685 875790 413549 943581 541138 895213 176409 856691 983363 722150 055628 034453 256180 117540 > 4²³¹ [i]
