(248−130, 248, 765)-Net in Base 3 — Upper bound on s

There is no (118, 248, 766)-net in base 3, because

the generalized Rao bound for nets shows that 3^mÂ â‰¥ 21847 584075 500781 849011 319151 742053 436148 871124 769014 778003 836635 105457 859633 145594 099587 071647 831870 165013 990916 302205 > 3²⁴⁸ [i]
