(119−66, 119, 116)-Net in Base 2 — Upper bound on s
There is no (53, 119, 117)-net in base 2, because
- 8 times m-reduction [i] would yield (53, 111, 117)-net in base 2, but
- extracting embedded orthogonal array [i] would yield OA(2111, 117, S2, 58), but
- adding a parity check bit [i] would yield OA(2112, 118, S2, 59), but
- the (dual) Plotkin bound shows that M ≥ 83076 749736 557242 056487 941267 521536 / 15 > 2112 [i]
- adding a parity check bit [i] would yield OA(2112, 118, S2, 59), but
- extracting embedded orthogonal array [i] would yield OA(2111, 117, S2, 58), but
