My apologies! It's even more emberrasing given the fact that I looked up the website, knowing that I _always_ swap them after having written too many `tx-listen` in my career. They expanded their work to wider relations and made the whole framework a lot more penetrable. I think they over-complicate things a bit with their forward-extension, so I'm keeping every column twice (still much better than all permutations), which in turn allows for ad-hoc cardinality estimation. Also the 1 based indexing with inclusive ranges is really not doing them any favours. Most formula become much more streamlined and simpler with 0 based indexing and exclusive ranges.
