      - OOA 3-folding [i] based on linear OA(3²¹¹, large, F₃, 22) (dual of [large, large−211, 23]-code), using
        the primitive expurgated narrow-sense BCH-code C(I) with length 14348906Â = 3¹⁵âˆ’1, defining interval IÂ =Â [0,21], and designed minimum distance dÂ â‰¥Â |I|+1Â =Â 23 [i]

(202, 224, large)-Net in Base 3 — Upper bound on s

There is no (202, 224, large)-net in base 3, because

20 times m-reduction [i] would yield (202, 204, large)-net in base 3, but
- mutually orthogonal hypercube bound [i]
