An inclusive measurement of the average multiplicity of View the MathML source pairs from gluons, View the MathML source, in hadronic Z0 events collected by the DELPHI experiment at LEP, is presented. A counting technique, based on jet b-tagging in 4-jet events, has been used. Looking for secondary bottom production in events with production of any primary flavour, by requiring two b-tagged jets in well defined topological configurations, gave View the MathML source. This result was checked with a different method designed to select events with four b quarks in the final state. Agreement within the errors was found.
