(24, 24+35, 291168)-Net in Base 81 — Upper bound on s
There is no (24, 59, 291169)-net in base 81, because
- 1 times m-reduction [i] would yield (24, 58, 291169)-net in base 81, but
- the generalized Rao bound for nets shows that 81m ≥ 492 194541 120068 923043 339502 822332 011583 619959 754508 142766 921228 773088 729860 489303 324434 014602 263671 764502 485841 > 8158 [i]
