(138−86, 138, 2410)-Net in Base 9 — Upper bound on s

There is no (52, 138, 2411)-net in base 9, because

the generalized Rao bound for nets shows that 9^mÂ â‰¥ 488366 021360 337723 208420 941454 002508 730422 821355 999772 221469 010972 818134 598923 353900 773155 877459 639000 932823 347988 517565 618919 174985 > 9¹³⁸ [i]
