(123, 256, 1741)-Net in Base 4 — Upper bound on s
There is no (123, 256, 1742)-net in base 4, because
- 1 times m-reduction [i] would yield (123, 255, 1742)-net in base 4, but
- the generalized Rao bound for nets shows that 4m ≥ 3438 781611 645674 280399 639288 332315 508862 368568 849955 343882 969915 322306 381967 844243 589978 162869 216117 124717 264373 505962 227395 513250 135574 645871 494581 821274 > 4255 [i]
