The following list corrects misprints that occurred in this article when preparing the author's original manuscript for publication.

1.	Author correspondence: Department of Mathematics and Statistics, University of Regina, Regina, Saskatchewan, S4S 0A2, Canada; E-mail: [email protected].
2.	The second displayed formula of page 22 should read
3.	In page 25, the correct reference is (Burnside, 1911, Sec. 88).
4.	The last three conditions on page 25 should read (c4) A(nm) = A(n)  B(n) A(m) for all n, m ∈ N. (c5) C(x y) = C(x)  D(x) C(y) for all x, y ∈ X. (c6)  for all x ∈ X, n ∈ N.
5.	Property (p2) is being defined in Theorem 3.4, page 26, as follows: (p2) If r, s ∈ R and rs = 1 then sr = 1.
6.	Property (p3) is being defined in Corollary 3.5, page 27, as follows: (p3) R + is characteristic in G = R + ⋊ U.
7.	The last displayed formula of page 28 should read
8.	The groups investigated by Sah in page 29 are of the form R + ⋊ U rather than R + × U.
