      1. linear OA(5¹³¹, 3126, F₅, 33) (dual of [3126, 2995, 34]-code), using the expurgated narrow-sense BCH-code C(I) with length 3126Â | 5¹⁰âˆ’1, defining interval IÂ =Â [0,16], and minimum distance dÂ â‰¥ |{−16,−15,…,16}|+1Â =Â 34 (BCH-bound) [i]

(100, 100+33, 993061)-Net in Base 5 — Upper bound on s

There is no (100, 133, 993062)-net in base 5, because

1 times m-reduction [i] would yield (100, 132, 993062)-net in base 5, but
- the generalized Rao bound for nets shows that 5^mÂ â‰¥ 183 671830 664931 236497 866206 389873 192180 705594 354744 355156 397075 778286 930957 678349 237067 007745 > 5¹³² [i]
