(121−72, 121, 2190)-Net in Base 8 — Upper bound on s

There is no (49, 121, 2191)-net in base 8, because

the generalized Rao bound for nets shows that 8^mÂ â‰¥ 18 895919 519088 388141 269460 834527 709954 896199 846573 039138 060667 320972 784813 232036 031671 846826 833348 003874 618732 > 8¹²¹ [i]
