    "abstract": "In this note a very crude but simple approximation to the set of separable\nstates in an arbitrary simplex of commutative states is given using the fact\nthat on the lines connecting the maximally mixed state and an arbitrary pure\nstate the positivity of the partial transpose is both necessary and sufficient\ncondition for separability of states. The lower limit to the volume of\nseparable states in a simplex is slightly improved.",
