(140−80, 140, 3237)-Net in Base 8 — Upper bound on s

There is no (60, 140, 3238)-net in base 8, because

the generalized Rao bound for nets shows that 8^mÂ â‰¥ 2 740216 366345 513736 489803 722622 572389 414701 818433 333967 196392 687862 929854 089532 439195 785262 554733 164769 796406 850130 463837 186256 > 8¹⁴⁰ [i]
