This page intended to present some calculations I have done with Piotr Kobak in the exceptional Lie algebra G2. In our paper on `HyperKähler Potentials in Cohomogeneity Two' we refer here for details of the calculations in the G2 case. These were performed using Maple.
An earlier version of the above code that is not so thorough or readable is also available from this page.
The derivation of the potential is available in postscript or as a Maple worksheet. The latter requires a Maple file of routines, which is currently partially documented and is available as a Noweb file.
