We include in the microfiche section of this issue a catalogue of all the different geometric configurations which may be constructed from zz points, zz S 8, by specifying their points, lines, planes, . . . , colines, copoints, their flats of each rank. It suffices to list the copoints of each combinatorial geometry G, because the colines of G are the copoints of a geometry earlier in the list, which may be located by deleting one component of the designator of G.
