Construction

Construction of a [[43,27,4]] 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]:  [[40, 27, 4]] quantum code over GF(2^2)
     Subcode of [1]
[3]:  [[43, 27, 4]] quantum code over GF(2^2)
     ExtendCode [2] by 3
