(137, 137+110, 3550)-Net in Base 4 — Upper bound on s
There is no (137, 247, 3551)-net in base 4, because
- the generalized Rao bound for nets shows that 4m ≥ 51149 692853 311999 375695 855285 997591 708137 363437 618921 419877 481000 046732 329276 533958 602818 962220 158146 594513 922340 383384 231742 115252 172525 057768 148792 > 4247 [i]
