(140−56, 140, 52870)-Net in Base 8 — Upper bound on s

There is no (84, 140, 52871)-net in base 8, because

the generalized Rao bound for nets shows that 8^mÂ â‰¥ 2 708437 922562 869322 100463 764689 588395 283200 151189 322228 448106 233011 163957 953613 717072 449298 881708 988959 570576 593736 360734 778512 > 8¹⁴⁰ [i]
