Fractions of extragalactic classes derived thanks to our revised analysis of the 3PBC. Individual classes have the following representation: 129 blz (~15.9%), gal 10 (~1.2%), 27 clu (~3.3%), 26 qso (~3.2%), 25 rdg (~3.1%), and 593 sey (~73.2%). We note that the liner, xbong, and sbg subclasses are omitted because of their small contribution (1, 4, and 5 members each, respectively).
