(234−124, 234, 1442)-Net in Base 4 — Upper bound on s

There is no (110, 234, 1443)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 766 488398 592777 903092 850273 266286 670117 381500 783130 717155 281337 343550 469670 452780 294685 886901 254065 009908 057615 227633 894514 188598 859669 746400 > 4²³⁴ [i]
