There is no linear OOA(2175, 228, F2, 6, 83) (dual of [(228, 6), 1193, 84]-NRT-code), because 4 times depth reduction would yield linear OOA(2175, 228, F2, 2, 83) (dual of [(228, 2), 281, 84]-NRT-code), but
- 1 step m-reduction [i] would yield linear OA(2174, 228, F2, 82) (dual of [228, 54, 83]-code), but
- construction Y1 [i] would yield
- linear OA(2173, 208, F2, 82) (dual of [208, 35, 83]-code), but
- construction Y1 [i] would yield
- linear OA(2172, 196, F2, 82) (dual of [196, 24, 83]-code), but
- adding a parity check bit [i] would yield linear OA(2173, 197, F2, 83) (dual of [197, 24, 84]-code), but
- OA(235, 208, S2, 12), but
- discarding factors would yield OA(235, 173, S2, 12), but
- the Rao or (dual) Hamming bound shows that M ≥ 35365 229344 > 235 [i]
- discarding factors would yield OA(235, 173, S2, 12), but
- linear OA(2172, 196, F2, 82) (dual of [196, 24, 83]-code), but
- construction Y1 [i] would yield
- OA(254, 228, S2, 20), but
- discarding factors would yield OA(254, 195, S2, 20), but
- the Rao or (dual) Hamming bound shows that M ≥ 18304 094847 646336 > 254 [i]
- discarding factors would yield OA(254, 195, S2, 20), but
- linear OA(2173, 208, F2, 82) (dual of [208, 35, 83]-code), but
- construction Y1 [i] would yield
Mode: Bound (linear).
