(234−66, 234, 81515)-Net in Base 4 — Upper bound on s

There is no (168, 234, 81516)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 762 211908 312291 840222 815500 594739 041745 915606 707666 417317 303025 638181 042592 417115 040458 997532 454499 820286 873248 877055 905319 617606 338223 092143 > 4²³⁴ [i]
