QECC [[15,5,4]]

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