upper bound:5

Construction

Construction of a [[59,44,4]] quantum code:
[1]:  [[62, 50, 4]] Quantum code over GF(2^2)
     quasicyclic code of length 62 stacked to height 2 with 4 generating polynomials
[2]:  [[56, 44, 4]] Quantum code over GF(2^2)
     Shortening of [1] at { 8, 11, 13, 47, 50, 52 }
[3]:  [[59, 44, 4]] Quantum code over GF(2^2)
     ExtendCode [2] by 3
