(234−138, 234, 917)-Net in Base 4 — Upper bound on s

There is no (96, 234, 918)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 778 709761 381797 759434 902544 358066 658491 626008 165954 510363 273254 343867 157112 389946 077903 637301 491797 286611 534802 468116 138676 161302 063563 889990 > 4²³⁴ [i]
