  I investigate some properties of proposed definitions for subsystem/mixed
state complexity and uncomplexity. A very strong dependence arises on the
density matrix's degeneracy which gives a large separation in the scaling of
maximum subsystem complexity with number of qubits (linear compared to
exponential). I also investigate several cases where the uncomplexity of
quantum states are superadditive and present some challenges and progress in
showing that the relation holds in complete generality.
