(120, 120+126, 825)-Net in Base 3 — Upper bound on s

There is no (120, 246, 826)-net in base 3, because

the generalized Rao bound for nets shows that 3^mÂ â‰¥ 2391 050986 661040 503938 846059 474316 844144 303105 406791 560209 224031 858120 563912 897309 910933 659226 979294 786372 440978 464601 > 3²⁴⁶ [i]
