(47, 47+63, 1917)-Net in Base 7 — Upper bound on s
There is no (47, 110, 1918)-net in base 7, because
- 1 times m-reduction [i] would yield (47, 109, 1918)-net in base 7, but
- the generalized Rao bound for nets shows that 7m ≥ 130 715298 713770 999010 943736 051741 988830 709141 300123 954469 268723 471567 233101 078917 710963 788785 > 7109 [i]
