Abstract

Let SnS_n be the symmetric group of nn letters; Landau considered the function g(n)g(n) defined as the maximal order of an element of SnS_n. This function is non-decreasing. Let us define the sequence n1=1,n2=2,n3=3,n4=4,n5=5,n6=7,...,nkn_1=1, n_2=2, n_3=3, n_4=4,n_5=5,n_6=7, ...,n_k such that g(nk)>g(nk1)g(n_k) > g(n_k -1). It is known that limsupnk+1nk=infinitylim sup n_{k+1}-n_k =infinity. Here it is shown that $lim inf n_{k+1}-n_k is finite.
