(91−49, 91, 432)-Net over F₃₂ — Digital

Digital (42, 91, 432)-net over F₃₂, using

Gilbertâ€“VarÅ¡amov bound [i]

(91−49, 91, 139403)-Net in Base 32 — Upper bound on s

There is no (42, 91, 139404)-net in base 32, because

1 times m-reduction [i] would yield (42, 90, 139404)-net in base 32, but
- the generalized Rao bound for nets shows that 32^mÂ â‰¥ 2907 356578 379995 286422 678625 960568 552048 649703 957894 081930 382438 368573 846901 194143 169285 475582 453612 494776 300216 529382 684677 470144 504552 > 32⁹⁰ [i]
