(110−37, 110, 165001)-Net in Base 7 — Upper bound on s
There is no (73, 110, 165002)-net in base 7, because
- 1 times m-reduction [i] would yield (73, 109, 165002)-net in base 7, but
- the generalized Rao bound for nets shows that 7m ≥ 130 536523 212060 437356 150936 929889 641327 469067 917642 870679 032189 638035 902694 994644 114420 478805 > 7109 [i]
