(18, 18+27, 15235)-Net in Base 27 — Upper bound on s
There is no (18, 45, 15236)-net in base 27, because
- 1 times m-reduction [i] would yield (18, 44, 15236)-net in base 27, but
- the generalized Rao bound for nets shows that 27m ≥ 955 220445 405112 855441 055141 215370 190043 015936 559852 299554 744009 > 2744 [i]
