Thanks for the link to Kiparsky's paper on mAheshvarasutraNi. Starting from the system of grouping and ordering, sandhi rules became straightforward to understand. When I first learned the sutras in school, we were presented with a lot of hand-waving and circular reasoning (sandhi rules- sutra grouping - sandhi rules) about why they were ordered in that seemingly arbitrary manner. It is cool that Kiparsky has solved the inverse problem of figuring out Panini's generative system for the grouping and ordering of syllables!
