(132, 205, 445)-Net over F₄ — Digital

Digital (132, 205, 445)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(132, 205, 12253)-Net in Base 4 — Upper bound on s

There is no (132, 205, 12254)-net in base 4, because

1 times m-reduction [i] would yield (132, 204, 12254)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 662 814722 744409 844543 816464 434542 021692 485780 877615 903416 299017 763963 899069 231043 457490 825629 776523 286009 408722 070608 223562 > 4²⁰⁴ [i]
