- 39 step Varšamov–Edel lengthening with (ri) = (3, 1, 0, 1, 0, 0, 0, 1, 5 times 0, 1, 6 times 0, 1, 8 times 0, 1, 9 times 0) [i] based on linear OA(435, 85, F4, 16) (dual of [85, 50, 17]-code), using
(28, 28+16, 2563)-Net in Base 4 — Upper bound on s
There is no (28, 44, 2564)-net in base 4, because
- the generalized Rao bound for nets shows that 4m ≥ 309 836009 889448 696207 906240 > 444 [i]
