Bounds on [[21,17]]2

lower bound:2
upper bound:2

Construction

Construction of a [[21,17,2]] quantum code:
[1]:  [[20, 18, 2]] quantum code over GF(2^2)
     Distance two code
[2]:  [[20, 17, 2]] quantum code over GF(2^2)
     Subcode of [1]
[3]:  [[21, 17, 2]] quantum code over GF(2^2)
     ExtendCode [2] by 1

    stabilizer matrix:

      [1 0 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 0 0|0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0]
