I was not claiming "K(n)<c" is true in my example. I thought you were
inferring your claim about the failure of Sigma_1-completeness from
the proposition that the Chaitin machine for T will give a witness to
K(n)<c. I showed this is not the case because the Chaitin machine is
programmed to find the *first* witness in T, not S.
Best,
Monroe
