Such finite groups had been partially classified by S. Williams, A. S. Kondrat'iev, N. Iiyori and H. Yamaki, M. Suzuki, W. Feit and J. G. Thompson, M. Herzog, Z. Arad, D. Chillag and others. In Classification of Finite Groups with a CC-subgroup'' [Communications in Algebra 32 (2004) 2087--2098] the present authors, having taken all this work into account, classified all finite groups containing a CC-subgroup. \endgraf As an application, in the present paper, we classify totally disconnected topologically locally finite groups, containing a topological analogue of a CC-subgroup. Keywords: CC-subgroups, prime graph, compactness conditions, locally compact groups. MSC: 22D05; 20E18, 20F50 [ Fulltext-pdf  (209  KB)] for subscribers only.
