(21, 77, 25003)-Net in Base 81 — Upper bound on s
There is no (21, 77, 25004)-net in base 81, because
- the generalized Rao bound for nets shows that 81m ≥ 898 209505 244884 693658 298651 583358 345708 944150 331874 924380 000919 414040 500064 118516 843895 294186 533918 482071 827675 035633 893061 271582 286447 391610 440961 > 8177 [i]
