Abstract
For an arbitrary link , Sarkar-Scaduto-Stoffregen construct a family of spatial refinements of even and odd Khovanov homology. We give a computation of on these spaces, determining their stable homotopy types for all knots K up to 11 crossings. We also prove that the Steenrod squares , defined by Sch\"utz do arise as Steenrod squares on these spaces.
