(4, 10, 37)-Net over F8 — Digital
Digital (4, 10, 37)-net over F8, using
- embedding of OOA with Gilbert–Varšamov bound [i] based on linear OOA(810, 37, F8, 2, 6) (dual of [(37, 2), 64, 7]-NRT-code), using
- OOA 2-folding [i] based on linear OA(810, 74, F8, 6) (dual of [74, 64, 7]-code), using
- a “GraX†code from Grassl’s database [i]
- OOA 2-folding [i] based on linear OA(810, 74, F8, 6) (dual of [74, 64, 7]-code), using
(4, 10, 264)-Net in Base 8 — Upper bound on s
There is no (4, 10, 265)-net in base 8, because
- the generalized Rao bound for nets shows that 8m ≥ 1081 110696 > 810 [i]
- extracting embedded orthogonal array [i] would yield OA(810, 265, S8, 6), but
- the linear programming bound shows that M ≥ 59 925125 398528 / 55515 > 810 [i]
