Menger property of 𝔽(ℝ,ord)
Determine whether the space 𝔽(ℝ,ord)—the subspace of the Vietoris power V(ℝ^ω) consisting of functions from ω to ℝ with finite range—is Menger, i.e., whether it satisfies the selection principle S_fin(𝒪, 𝒪).

We have not yet even been able to determine whether \mathbb F(\mathbb R, \mathrm{ord}) is Menger; if \mathbb F(\mathbb R, \mathrm{ord}) fails to be Menger, then Question \ref{question:MengerThing} would be answered in the negative.
