Abstract: In his study of the smoothings of p. l. manifolds, R. Thom considered the homotopy groups of a certain space $ {L_n}$ of p.l. homeomorphisms on an $ n$-simplex. N. H. Kuiper showed in 1965 that the higher homotopy groups of $ {L_n}$ were in general nontrivial. The main result in this paper is that $ {\pi _0}({L_2}) = {\pi _1}({L_2}) = 0$.

The proof of this result is based on a theorem of S. S. Cairns in 1944 on the deformation of rectilinear complexes in $ {R^2}$ and a theorem established in Part I of this paper.
