(106, 106+148, 1042)-Net in Base 4 — Upper bound on s

There is no (106, 254, 1043)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 861 697629 477327 753117 656347 712393 836146 527794 684395 197879 660331 198938 333567 248020 241235 033162 006111 361225 767811 136177 827667 546070 774892 809177 522644 049440 > 4²⁵⁴ [i]
