Information on Result #3063584
There is no (19, 143, 72)-net in base 4, because 3 times m-reduction would yield (19, 140, 72)-net in base 4, but
- extracting embedded OOA [i] would yield OOA(4140, 72, S4, 2, 121), but
- the (dual) Plotkin bound for OOAs shows that M ≥ 124 330809 102446 660538 845562 036705 210025 114037 699336 929360 115994 223289 874253 133343 883264 / 61 > 4140 [i]
