That sucks. Who's going to carry on the research? Perhaps @Jerry Russell should guest on MythVision to discuss @Richard Stanley 's work? I think they'd run with it and talk to other guests about it.As far as I know, Rick is the only person on the planet who can do the work he's doing. From time to time, he comes up with insights that I treasure. Every day that he's still working on these questions, is a gift.
