(219−118, 219, 1258)-Net in Base 4 — Upper bound on s

There is no (101, 219, 1259)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 738150 867948 881175 214184 179454 341538 731534 347513 100566 682654 607526 622600 493870 664077 481218 243468 828337 888238 715482 946542 467343 846288 > 4²¹⁹ [i]
