(67, 67+80, 6307)-Net in Base 9 — Upper bound on s

There is no (67, 147, 6308)-net in base 9, because

the generalized Rao bound for nets shows that 9^mÂ â‰¥ 188 315508 975451 791600 147952 646189 320877 885877 413937 360746 307198 924780 850050 477288 262320 218185 570748 668938 736253 893416 902393 203586 498307 373825 > 9¹⁴⁷ [i]
