embedding of OOA with Gilbertâ€“VarÅ¡amov bound [i] based on linear OA(5¹⁰⁴, 813, F₅, 31) (dual of [813, 709, 32]-code), using
- 708 step VarÅ¡amovâ€“Edel lengthening with (r_i)Â = (7, 4, 2, 1, 1, 2, 1, 1, 0, 1, 1, 0, 1, 1, 0, 1, 0, 1, 0, 1, 0, 1, 0, 0, 1, 0, 0, 1, 0, 0, 1, 0, 0, 1, 0, 0, 1, 0, 0, 0, 1, 0, 0, 0, 1, 0, 0, 0, 1, 0, 0, 0, 1, 4 times 0, 1, 4 times 0, 1, 4 times 0, 1, 5 times 0, 1, 5 times 0, 1, 5 times 0, 1, 6 times 0, 1, 7 times 0, 1, 6 times 0, 1, 8 times 0, 1, 8 times 0, 1, 8 times 0, 1, 9 times 0, 1, 9 times 0, 1, 10 times 0, 1, 11 times 0, 1, 12 times 0, 1, 12 times 0, 1, 13 times 0, 1, 14 times 0, 1, 14 times 0, 1, 16 times 0, 1, 17 times 0, 1, 17 times 0, 1, 19 times 0, 1, 20 times 0, 1, 21 times 0, 1, 22 times 0, 1, 24 times 0, 1, 25 times 0, 1, 27 times 0, 1, 28 times 0, 1, 30 times 0, 1, 32 times 0, 1, 33 times 0, 1, 35 times 0, 1, 38 times 0, 1, 40 times 0) [i] based on linear OA(5³¹, 32, F₅, 31) (dual of [32, 1, 32]-code or 32-arc in PG(30,5)), using
  - dual of repetition code with length 32 [i]

There is no (73, 104, 101218)-net in base 5, because

1 times m-reduction [i] would yield (73, 103, 101218)-net in base 5, but
- the generalized Rao bound for nets shows that 5^mÂ â‰¥ 986184 888439 282790 176924 269398 027940 685426 251278 727759 045094 798132 430249 > 5¹⁰³ [i]
