(240−122, 240, 829)-Net in Base 3 — Upper bound on s

There is no (118, 240, 830)-net in base 3, because

the generalized Rao bound for nets shows that 3^mÂ â‰¥ 3 433429 589729 276459 326477 824216 577558 954749 737984 291329 882322 222296 319790 825542 053438 870826 984035 330244 979562 013733 > 3²⁴⁰ [i]
