(255−132, 255, 1741)-Net in Base 4 — Upper bound on s

There is no (123, 255, 1742)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 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]
