Much ado about 248
M. C. Nucci, P. G. L. Leach
In this note we present three representations of a 248-dimensional Lie algebra, namely the algebra of Lie point symmetries admitted by a system of five trivial ordinary differentia…

Jacobi's last multiplier and the complete symmetry group of the Euler-Poinsot system
M. C. Nucci, P. G. L. Leach
The symmetry approach to the determination of Jacobi's last multiplier is inverted to provide a source of additional symmetries for the Euler-Poinsot system. These additional symme…

Linearisable third order ordinary differential equations and generalised Sundman transformations
N. Euler, T. Wolf, P. G. L. Leach +1
We calculate in detail the conditions which allow the most general third order ordinary differential equation to be linearised in X'''(T)=0 under the transformation X(T)=F(x,t), dT…
