(72, 72+87, 437)-Net in Base 3 — Upper bound on s

There is no (72, 159, 438)-net in base 3, because

1 times m-reduction [i] would yield (72, 158, 438)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 2615 509067 251018 994169 821698 849402 803939 175657 246240 620988 379080 779999 443217 > 3¹⁵⁸ [i]
