(228−66, 228, 63348)-Net in Base 4 — Upper bound on s

There is no (162, 228, 63349)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 186137 530119 411360 006493 401361 070110 211892 015497 190732 896177 773496 190122 132281 278657 081224 309442 541364 219266 409774 284136 454129 452080 873216 > 4²²⁸ [i]
