Here we compute analytically the multi-particle eccentricities, ϵ_m{2n}, for systems dominated by fluctuations, such as proton–nucleus collisions at the Large Hadron Collider. In particular, we derive a general relation for $$\langle$$ ϵ$$2n\atop{2}$$ $$\rangle$$. We further discuss the relations between various multi-particle eccentricities and demonstrate that ϵ₂{2}>ϵ₂{4}≃ϵ₂{6}≃ϵ₂{8}, in agreement with recent numerical calculations in a Glauber model.
