  Given a fixed knot P in a solid torus and any knot K in S^3, one can form the
satellite of K with pattern P. This operation induces a self-map of the
concordance group of knots in S^3. It has been proved by Dai, Hedden, Mallick,
and Stoffregen that in the smooth category there exist P for which this
function is rank-expanding; that is, for some K, the set {P(nK)} generates an
infinite rank subgroup. Here we demonstrate that similar examples exist in the
case of the topological locally flat concordance group. Such examples cannot
exist in the algebraic concordance group.
