Information on Result #3149637
There is no digital (60, 221, 320)-net over F4, because 1 times m-reduction would yield digital (60, 220, 320)-net over F4, but
- extracting embedded orthogonal array [i] would yield linear OA(4220, 320, F4, 160) (dual of [320, 100, 161]-code), but
- residual code [i] would yield OA(460, 159, S4, 40), but
- the linear programming bound shows that M ≥ 89256 467878 907972 172600 180176 154060 802582 684769 875981 969312 131469 276806 223240 396340 011634 339610 624000 / 64975 225388 099566 116025 141010 137689 743517 140250 845468 320822 687201 > 460 [i]
