Finite designation catalogs may be indexed by numerical words of varying length.

OAI.TwoPointCorrelations.designation_catalog_weightline 15Source documentation
Each admissible designation set is a subset of all slots. The complete catalog therefore costs at most one binary choice per slot.

The threshold is uniform in the finite catalog and in its index type. It can therefore be used for word lengths and prime pools varying with L.
