(124, 124+69, 416)-Net over F₄ — Digital

Digital (124, 193, 416)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(124, 124+69, 11301)-Net in Base 4 — Upper bound on s

There is no (124, 193, 11302)-net in base 4, because

1 times m-reduction [i] would yield (124, 192, 11302)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 39 402484 498450 867905 795098 892307 289945 095679 817308 159478 778297 192028 092635 550382 201685 644379 801451 865302 126987 335730 > 4¹⁹² [i]
