arrangements-by-exponent
One row per counted pair, with a mark under each exponent that reaches it. Indexed this way the table has 20 arrangements rather than 15 destinations, because the same pair occurs at several divergences as the rise moves along its own rung and the same divergence occurs with several pairs. four arrangements are reached only by the two steep falloffs and two only by the two shallow ones, which is the same question asked in both directions.
Drawn at its defaults, in every destination, counted. It takes no options at all, so every essay calling it gets this exact drawing.
