We also give a result concerning the relative projectivity of the reduced Lefschetz module associated to the aformentioned 2-local geometry.20 pagesGroup TheoryAlgebraic Topology20G05 (Primary); 20C20, 51D20 (Secondary)On a homotopy relation between the 2-local geometry and the Bouc complex for the sporadic group Co3text
