Abstract
Let be the subgroup of the smooth knot concordance group generated by topologically slice knots. Endo showed that contains an infinite-rank subgroup, and Livingston and Manolescu-Owens showed that contains a summand. We show that in fact contains a summand. The proof relies on the knot Floer homology package of Ozsváth–Szabó and the concordance invariant .
