Digital (134, 154, 524300)-net over F4, using embedding of OOA with Gilbert–Varšamov bound based on linear OOA(4154, 524300, F4, 2, 20) (dual of [(524300, 2), 1048446, 21]-NRT-code), using
- 1 times NRT-code embedding in larger space [i] based on linear OOA(4152, 524299, F4, 2, 20) (dual of [(524299, 2), 1048446, 21]-NRT-code), using
- OOA 2-folding [i] based on linear OA(4152, 1048598, F4, 20) (dual of [1048598, 1048446, 21]-code), using
- construction X4 applied to Ce(20) ⊂ Ce(17) [i] based on
- linear OA(4151, 1048576, F4, 21) (dual of [1048576, 1048425, 22]-code), using an extension Ce(20) of the primitive narrow-sense BCH-code C(I) with length 1048575 = 410−1, defining interval I = [1,20], and designed minimum distance d ≥ |I|+1 = 21 [i]
- linear OA(4131, 1048576, F4, 18) (dual of [1048576, 1048445, 19]-code), using an extension Ce(17) of the primitive narrow-sense BCH-code C(I) with length 1048575 = 410−1, defining interval I = [1,17], and designed minimum distance d ≥ |I|+1 = 18 [i]
- linear OA(421, 22, F4, 21) (dual of [22, 1, 22]-code or 22-arc in PG(20,4)), using
