    Left 3-Engel elements in groups of exponent 60

    Let G be a group and let xG be a left 3-Engel element of order dividing 60. Suppose furthermore that xG has no elements of order 8, 9 and 25. We show that x is then contained in the locally nilpotent radical of G. In particular, all the left 3-Engel elements of a group of exponent 60 are contained in the locally nilpotent radical.

    ON CERTAIN PAIRS OF NON-ENGEL ELEMENTS IN FINITE GROUPS

    Let G be a group and h, g ∈ G. The 2-tuple (h, g) is said to be an n-Engel pair if h = [h,n g] and g = [g,n h]. In this paper, we will study the subgroup generated by the n-Engel pair under certain conditions.

    ON n-ENGEL PAIR SATISFYING CERTAIN CONDITIONS

    Let G be a group and h, g ∈ G. The 2-tuple (h, g) is said to be an n-Engel pair, n ≥ 2, if h = [h,n g], g = [g,n h] and h ≠ 1. In this paper, we prove that if (h, g) is an n-Engel pair, hgh-2gh = ghg and ghg-2hg = hgh, then n = 2k where k = 4 or k ≥ 6. Furthermore, the subgroup generated by {h, g} is determined for k = 4, 6, 7 and 8.

    On the existence of Engel pairs in certain linear groups

    Let G be a group and h,gG. The 2-tuple (h,g) is said to be an n-Engel pair, n2, if h=[h,ng], g=[g,nh] and h1. Let SL(2,F) be the special linear group of degree 2 over the field F. In this paper, we show that given any field L, there is a field extension F of L with [F:L]6 such that SL(2,F) has an n-Engel pair for some integer n4. We will also show that SL(2,F) has a 5-Engel pair if F is a field of characteristic p±1mod5.
