Query: Knot Floer Filtration Classes of Topologically Slice Knots   The knot Floer complex and the concordance invariant $\varepsilon$ can be
used to define a filtration on the smooth concordance group. We exhibit an
ordered subset of this filtration that is isomorphic to $\mathbb{N} \times
\mathbb{N}$ and consists of topologically slice knots.
