Best Known (87, 87+11, s)-Nets in Base 4

Digital (87, 98, 1677720)-net over F₄, using

4¹ times duplication [i] based on digital (86, 97, 1677720)-net over F₄, using
- net defined by OOA [i] based on linear OOA(4⁹⁷, 1677720, F₄, 11, 11) (dual of [(1677720, 11), 18454823, 12]-NRT-code), using
  - OOA 5-folding and stacking with additional row [i] based on linear OA(4⁹⁷, 8388601, F₄, 11) (dual of [8388601, 8388504, 12]-code), using
    - discarding factors / shortening the dual code based on linear OA(4⁹⁷, large, F₄, 11) (dual of [large, large−97, 12]-code), using
