Deveci, Ö.; Karaduman, E. Lehmer sequences in finite groups. (English) Zbl 1492.11020 Ukr. Math. J. 68, No. 2, 193-202 (2016) and Ukr. Mat. Zh. 68, No. 2, 175-182 (2016). Summary: We study the Lehmer sequences modulo \(m\). Moreover, we define the Lehmer orbit and the basic Lehmer orbit of a 2-generator group \(G\) for a generating pair \((x, y) \in G\) and examine the lengths of the periods of these orbits. Furthermore, we obtain the Lehmer lengths and the basic Lehmer lengths of the Fox groups \(G_{1,t}\) for \(t \geq 3\).
