Information on Result #594150
There is no linear OOA(267, 82, F2, 7, 33) (dual of [(82, 7), 507, 34]-NRT-code), because 5 times depth reduction would yield linear OOA(267, 82, F2, 2, 33) (dual of [(82, 2), 97, 34]-NRT-code), but
- 1 step m-reduction [i] would yield linear OA(266, 82, F2, 32) (dual of [82, 16, 33]-code), but
- construction Y1 [i] would yield
- linear OA(265, 76, F2, 32) (dual of [76, 11, 33]-code), but
- construction Y1 [i] would yield
- linear OA(264, 72, F2, 32) (dual of [72, 8, 33]-code), but
- adding a parity check bit [i] would yield linear OA(265, 73, F2, 33) (dual of [73, 8, 34]-code), but
- “BJV†bound on codes from Brouwer’s database [i]
- adding a parity check bit [i] would yield linear OA(265, 73, F2, 33) (dual of [73, 8, 34]-code), but
- OA(211, 76, S2, 4), but
- discarding factors would yield OA(211, 64, S2, 4), but
- the Rao or (dual) Hamming bound shows that M ≥ 2081 > 211 [i]
- discarding factors would yield OA(211, 64, S2, 4), but
- linear OA(264, 72, F2, 32) (dual of [72, 8, 33]-code), but
- construction Y1 [i] would yield
- OA(216, 82, S2, 6), but
- discarding factors would yield OA(216, 74, S2, 6), but
- the Rao or (dual) Hamming bound shows that M ≥ 67600 > 216 [i]
- discarding factors would yield OA(216, 74, S2, 6), but
- linear OA(265, 76, F2, 32) (dual of [76, 11, 33]-code), but
- construction Y1 [i] would yield
