(46, 46+118, 290)-Net over F4 — Upper bound on s (digital)
There is no digital (46, 164, 291)-net over F4, because
- 2 times m-reduction [i] would yield digital (46, 162, 291)-net over F4, but
- extracting embedded orthogonal array [i] would yield linear OA(4162, 291, F4, 116) (dual of [291, 129, 117]-code), but
- residual code [i] would yield OA(446, 174, S4, 29), but
- the linear programming bound shows that M ≥ 8506 289708 537907 430011 501124 929257 400094 961052 942336 000000 / 1 703346 550862 338223 360728 253441 > 446 [i]
- residual code [i] would yield OA(446, 174, S4, 29), but
- extracting embedded orthogonal array [i] would yield linear OA(4162, 291, F4, 116) (dual of [291, 129, 117]-code), but
(46, 46+118, 291)-Net in Base 4 — Upper bound on s
There is no (46, 164, 292)-net in base 4, because
- 9 times m-reduction [i] would yield (46, 155, 292)-net in base 4, but
- extracting embedded orthogonal array [i] would yield OA(4155, 292, S4, 109), but
- 8 times code embedding in larger space [i] would yield OA(4163, 300, S4, 109), but
