Abstract

The present paper is related to some recent studies in Abdollahi and Russo [‘On a problem of P. Hall for Engel words’, Arch. Math. (Basel) \(97\) (2011), 407–412] and Fernández-Alcober et al. [‘A note on conciseness of Engel words’, Comm. Algebra \(40\) (2012), 2570–2576] on the position of the \(n\)--Engel marginal subgroup \(E^*_n(G)\) of a group \(G\), when \(n=3,4\). Describing the size of \(E^*_n(G)\) for \(n=3,4\), we show some generalisations of classical results on the partial margins of \(E^*_3(G)\) and \(E^*_4(G)\). DOI: 10.1017/S0004972714000094
