Information on Result #564043
There is no linear OOA(1687, 175, F16, 2, 81) (dual of [(175, 2), 263, 82]-NRT-code), because 1 step m-reduction would yield linear OA(1686, 175, F16, 80) (dual of [175, 89, 81]-code), but
- construction Y1 [i] would yield
- linear OA(1685, 92, F16, 80) (dual of [92, 7, 81]-code), but
- construction Y1 [i] would yield
- OA(1684, 86, S16, 80), but
- the (dual) Plotkin bound shows that M ≥ 4 479489 484355 608421 114884 561136 888556 243290 994469 299069 799978 201927 583742 360321 890761 754986 543214 231552 / 27 > 1684 [i]
- OA(167, 92, S16, 6), but
- discarding factors would yield OA(167, 80, S16, 6), but
- the Rao or (dual) Hamming bound shows that M ≥ 278 002201 > 167 [i]
- discarding factors would yield OA(167, 80, S16, 6), but
- OA(1684, 86, S16, 80), but
- construction Y1 [i] would yield
- OA(1689, 175, S16, 83), but
- discarding factors would yield OA(1689, 165, S16, 83), but
- the linear programming bound shows that M ≥ 15352 684767 685611 086882 809761 984160 188561 571509 004484 738285 092713 831920 008077 971129 525920 055364 921813 182353 415776 911815 913281 106245 860502 560348 270257 729557 233664 / 103836 312412 686023 017550 716368 186316 554556 371946 618739 > 1689 [i]
- discarding factors would yield OA(1689, 165, S16, 83), but
- linear OA(1685, 92, F16, 80) (dual of [92, 7, 81]-code), but
Mode: Bound (linear).
