(42, 140, 1007)-Net in Base 8 — Upper bound on s

There is no (42, 140, 1008)-net in base 8, because

the generalized Rao bound for nets shows that 8^mÂ â‰¥ 2 717527 705728 710732 222819 377596 305053 025164 832202 475860 875608 783321 938112 471033 291124 827154 570911 782572 325042 008161 054832 022684 > 8¹⁴⁰ [i]
