Symbolic derivation of Runge–Kutta–Nyström order conditions

Runge–Kutta–Nyström methods possess a separate theory from the classical Runge–Kutta schemes for the derivation of their order conditions and principal truncation error terms. A new code using the Mathematica programming language properties and tensor products is proved very efficient in this task....
