contents In quantum field theory study, Grassmannian manifolds $\text{Gr}(4,n)$ are closely related to $D{=}4$ kinematics input for $n$-particle scattering processes, whose combinatorial and geometrical structures have been widely applied in studying conformal invariant physical theories and their scattering amplitudes. Recently, \cite{HLY21} observed that constraining $D{=}4$ kinematics input to its $D{=}3$ subspace can be interpreted as folding Grassmannian cluster algebras $\mathbb{C}[\text{Gr}(4,n)]$. In this paper, we deduce general expressions for these constraints in terms of Plücker variables of $\text{Gr}(4,n)$ directly from $D{=}3$ subspace definition, and propose a series of initial quivers for algebra $\mathbb{C}[\text{Gr}(4,n)]$ whose folding conditions exactly meet the constraints, which proves the observation finally.
