A first numerical simulation of the clustering properties of a possible highly homogeneous collisionless component of mass in the pancake theory of galaxy formation is presented for scales greater than one wavelength. The cloud in cell method is used to suppress two-body effects and an initial perturbation spectrum with a lower cutoff in wavelength simulates conditions in the adiabatic theory of galaxy formation. Collisionless particles are used on the hypothesis that hidden mass existed prior to galaxy formation. It is found that a cell structure is formed on a scale roughly coincident with the cutoff, confirming previous studies of this type. There is no fragmentation or disruption of the large-scale inhomogeneities unless ad hoc small-scale perturbations are added. Although hierarchical clumping tends to progressively destroy the cell structure, such a structure can continue to exist to z = 0 in a closed model.
