Abstract

If \( T \) is any finite higher commutator in a ring \( R \), for example \( T = [[R, R], [R, R]] \), and if \( T \) has minimal cardinality so that the ideal generated by \( T \) is infinite, then \( T \) is in the center of \( R \) and \( T^2 = 0 \). Also, if \( T \) is any finite, higher commutator containing no nonzero nilpotent element then \( T \) generates a finite ideal. DOI: 10.1017/S0004972713000890
