(74−60, 74, 5438)-Net in Base 64 — Upper bound on s

There is no (14, 74, 5439)-net in base 64, because

the generalized Rao bound for nets shows that 64^mÂ â‰¥ 45 491898 892803 601089 700091 067493 553966 892531 158002 821822 777307 836448 776718 169852 523682 191427 564326 466490 826612 520133 053525 230149 708755 > 64⁷⁴ [i]
