(172−120, 172, 1247)-Net in Base 8 — Upper bound on s

There is no (52, 172, 1248)-net in base 8, because

the generalized Rao bound for nets shows that 8^mÂ â‰¥ 216162 693324 720802 770387 272179 057952 067638 762473 575230 915403 802134 739620 146771 466993 230020 272935 713175 405289 064509 814392 370103 900405 913532 943723 785037 500066 > 8¹⁷² [i]
