Line 76:
does not contain the operator <math>-I^{\otimes n}</math>. The simultaneous
<math>+1</math>-[[eigenspace]] of the operators constitutes the ''codespace''. The
codespace has dimension <math>2^{k}</math> so that we can encode <math>k</math>

independent generators
Line 84:
The generators are
independent in the sense that none of them is a product of any other two (up
to a [[Quantum state|global phase]]). The operators <math>g_{1},\ldots,g_{n-k}</math> function in the same
way as a [[parity check matrix]] does for a classical [[linear block code]].
