(53, 72, 1892)-Net over F25 — Constructive and digital
Digital (53, 72, 1892)-net over F25, using
- (u, u+v)-construction [i] based on
- digital (8, 17, 156)-net over F25, using
- net defined by OOA [i] based on linear OOA(2517, 156, F25, 9, 9) (dual of [(156, 9), 1387, 10]-NRT-code), using

(53, 72, 122945)-Net over F25 — Digital
Digital (53, 72, 122945)-net over F25, using
(53, 72, large)-Net in Base 25 — Upper bound on s
There is no (53, 72, large)-net in base 25, because
- 17 times m-reduction [i] would yield (53, 55, large)-net in base 25, but
