(59, 59+164, 289)-Net over F4 — Upper bound on s (digital)
There is no digital (59, 223, 290)-net over F4, because
- extracting embedded orthogonal array [i] would yield linear OA(4223, 290, F4, 164) (dual of [290, 67, 165]-code), but
- residual code [i] would yield OA(459, 125, S4, 41), but
- the linear programming bound shows that M ≥ 6 098659 704705 486904 667441 402011 989050 548288 910427 912825 765842 283670 760248 415348 522730 039189 577335 282788 475369 967101 883338 375933 306396 897634 126855 141698 525692 111751 859853 590528 / 17 865783 539531 952003 937094 580988 623442 037272 256331 005047 247373 356459 142621 652981 139301 072409 181322 127802 625025 609129 027701 857126 610015 951793 > 459 [i]
- residual code [i] would yield OA(459, 125, S4, 41), but
(59, 59+164, 388)-Net in Base 4 — Upper bound on s
There is no (59, 223, 389)-net in base 4, because
- the generalized Rao bound for nets shows that 4m ≥ 184 374640 025215 147731 060650 772526 775245 516620 605142 254567 351576 690346 211620 265190 339121 711179 659733 249316 838144 975016 493084 664696 327120 > 4223 [i]
