- 196 step Varšamov–Edel lengthening with (ri) = (2, 0, 1, 4 times 0, 1, 11 times 0, 1, 25 times 0, 1, 52 times 0, 1, 97 times 0) [i] based on linear OA(5100, 3124, F5, 25) (dual of [3124, 3024, 26]-code), using
(82, 82+25, 1974852)-Net in Base 5 — Upper bound on s
There is no (82, 107, 1974853)-net in base 5, because
- 1 times m-reduction [i] would yield (82, 106, 1974853)-net in base 5, but
- the generalized Rao bound for nets shows that 5m ≥ 123 260138 532335 356286 448070 097295 891490 893530 431151 848503 124116 493772 211665 > 5106 [i]
