Construction

Construction of a [[27,14,4]] quantum code:
[1]:  [[40, 30, 4]] Quantum code over GF(2^2)
     quasicyclic code of length 40 stacked to height 2 with 16 generating polynomials
[2]:  [[24, 14, 4]] Quantum code over GF(2^2)
     Shortening of [1] at { 3, 5, 7, 8, 9, 10, 11, 12, 13, 15, 16, 17, 28, 30, 31, 34 }
[3]:  [[27, 14, 4]] Quantum code over GF(2^2)
     ExtendCode [2] by 3
