- linear OA(46, 7, F4, 6) (dual of [7, 1, 7]-code or 7-arc in PG(5,4)), using
- dual of repetition code with length 7 [i]
- linear OA(47, 7, F4, 7) (dual of [7, 0, 8]-code or 7-arc in PG(6,4)), using
- linear OA(4165, 4194303, F4, 20) (dual of [4194303, 4194138, 21]-code), using
- 1 times truncation [i] based on linear OA(4166, 4194304, F4, 21) (dual of [4194304, 4194138, 22]-code), using
