(237−108, 237, 3023)-Net in Base 4 — Upper bound on s
There is no (129, 237, 3024)-net in base 4, because
- the generalized Rao bound for nets shows that 4m ≥ 49359 242914 876043 536915 881523 815165 064987 587745 508420 470181 114641 554499 249505 051979 906394 105208 910255 555740 721451 127513 566450 548982 037707 425964 > 4237 [i]
