Wielandt series and defects of subnormal subgroups in finite soluble groups
Word distance on the discrete Heisenberg group
We establish an exact formula for the word distance on the discrete Heisenberg group ℍ₃ with its standard set of generators. This formula is then used to prove the almost connectedness of the spheres for this distance.
Words with intervening neighbours in infinite Coxeter groups are reduced.
W-perfect groups
In the present article we define W-paths of elements in a W-perfect group as a useful tools and obtain their basic properties.

-interpolation lattice-ordered groups
In [1], Jakubík showed that the class of -interpolation lattice-ordered groups forms a radical class, but left open the question of whether the class forms a torsion class. In this paper, we show that this class does indeed form a torsion class.
