(254−105, 254, 5685)-Net in Base 4 — Upper bound on s
There is no (149, 254, 5686)-net in base 4, because
- 1 times m-reduction [i] would yield (149, 253, 5686)-net in base 4, but
- the generalized Rao bound for nets shows that 4m ≥ 210 192651 010186 745498 897673 681797 202401 391163 710833 665841 036710 344244 217371 625006 747547 377347 046621 882779 566778 098730 256418 927578 847228 661026 025625 895253 > 4253 [i]
