(109, 109+140, 602)-Net in Base 3 — Upper bound on s

There is no (109, 249, 603)-net in base 3, because

the generalized Rao bound for nets shows that 3^mÂ â‰¥ 63583 386845 211401 225001 985522 087611 423406 406819 847785 643633 835058 493628 588413 222740 380789 630046 722004 123388 225247 202061 > 3²⁴⁹ [i]
