(112, 112+37, 31612)-Net in Base 3 — Upper bound on s

There is no (112, 149, 31613)-net in base 3, because

1 times m-reduction [i] would yield (112, 148, 31613)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 41125 096297 703818 411447 379122 851326 509433 082807 151570 758493 770151 909441 > 3¹⁴⁸ [i]
