QECC [[17,9,4]]

This pure code is based on a linear self-orthogonal code over GF(4) with generator matrix:
[  1   0   0   0   1 a^2 a^2   a   1   0 a^2 a^2   0   1   a a^2 a^2]
[  0   1   0   0 a^2 a^2   1   a   1   1   a   1 a^2 a^2   0   0   1]
[  0   0   1   0   1   0   0 a^2 a^2   1   a   1   1   a   1 a^2 a^2]
[  0   0   0   1 a^2 a^2   a   1   0 a^2 a^2   0   1   a a^2 a^2   1]
