        a function field by GarcÃa and Quoos [i]

(29, 29+12, 651)-Net over F₅ — Digital

Digital (29, 41, 651)-net over F₅, using

embedding of OOA with Gilbertâ€“VarÅ¡amov bound [i] based on linear OA(5⁴¹, 651, F₅, 12) (dual of [651, 610, 13]-code), using
- 18 step VarÅ¡amovâ€“Edel lengthening with (r_i)Â = (2, 0, 1, 4 times 0, 1, 10 times 0) [i] based on linear OA(5³⁷, 629, F₅, 12) (dual of [629, 592, 13]-code), using

    1. linear OA(5³⁷, 625, F₅, 12) (dual of [625, 588, 13]-code), using an extension C_e(11) of the primitive narrow-sense BCH-code C(I) with length 624Â = 5⁴âˆ’1, defining interval IÂ =Â [1,11], and designed minimum distance dÂ â‰¥Â |I|+1Â =Â 12 [i]
    2. linear OA(5³³, 625, F₅, 11) (dual of [625, 592, 12]-code), using an extension C_e(10) of the primitive narrow-sense BCH-code C(I) with length 624Â = 5⁴âˆ’1, defining interval IÂ =Â [1,10], and designed minimum distance dÂ â‰¥Â |I|+1Â =Â 11 [i]

        OA with only one run / dual of code without redundancy [i]

(29, 29+12, 44711)-Net in Base 5 — Upper bound on s

There is no (29, 41, 44712)-net in base 5, because

the generalized Rao bound for nets shows that 5^mÂ â‰¥ 45478 394897 576432 748962 288257 > 5⁴¹ [i]
