Order-three transfer for Williamson 2N-storage Runge-Kutta methods at arbitrary stage count

Williamson 2N-storage Runge-Kutta methods can be lifted to Lie groups by replacing each additive low-storage update with an exponential update. The complete three-stage, third-order family was known to retain order three, while the same-order claim for methods with more stages re...
