(103, 103+140, 1046)-Net in Base 4 — Upper bound on s

There is no (103, 243, 1047)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 208 864704 243211 929668 069859 577481 688518 501754 405542 322317 936338 757722 530842 530119 913210 244372 368391 541638 402413 446236 108692 991836 421927 421377 280880 > 4²⁴³ [i]
