COMMENTS

There is a related sequence which is presently too short to include: Highest minimal Lee distance of any Type (4^E)_II Euclidean linear even selfdual code over GF(4) of length 4n. This begins 4, 4, 8, 8, 8, then either 8 or 12, 12, 12, ...
The sequence continues: a(9) = either 6 or 7, a(10) = a(11) = 8, a(12) = 8, 9 or 10, ...
