(248−146, 248, 515)-Net in Base 3 — Upper bound on s

There is no (102, 248, 516)-net in base 3, because

the generalized Rao bound for nets shows that 3^mÂ â‰¥ 21229 497973 560301 467493 185235 364193 518672 991090 096583 629896 266967 547008 988446 451688 891344 550533 780278 882710 849472 682249 > 3²⁴⁸ [i]
