(72, 97, 87381)-Net over F32 — Constructive and digital
Digital (72, 97, 87381)-net over F32, using
- net defined by OOA [i] based on linear OOA(3297, 87381, F32, 25, 25) (dual of [(87381, 25), 2184428, 26]-NRT-code), using

(72, 97, large)-Net in Base 32 — Upper bound on s
There is no (72, 97, large)-net in base 32, because
- 23 times m-reduction [i] would yield (72, 74, large)-net in base 32, but
