(193−134, 193, 413)-Net in Base 4 — Upper bound on s

There is no (59, 193, 414)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 176 944750 802249 488966 942503 538263 012224 142366 426769 106352 027329 996181 885689 226971 122040 212845 555162 457678 269138 386500 > 4¹⁹³ [i]
