Query: Strongly t-logarithmic t-generating sets: Geometric properties of some
  soluble groups   We introduce the concept of a strongly t-logarithmic t-generating set for a
Z[t,t^{-1}]-module, which enables us to prove that a large class of soluble
groups are not almost convex. We also prove some results about dead-end depth.
