We show that the composition of not only two SO(3,1) boosts, but also that of two SO(n,1) boosts for anyn ≥ 2, is basically an SO(2,1) problem and hence can be analysed completely using SL(2,R) matrices. By computing the expression for the Thomas/Wigner angle directly using SL(2,R) matrices we show that this approach results in considerable economy of algebra.
