The Catalan numbers give the number of ways to tile an n-sized stair case with exactly n rectangles. 

That’s so interesting!

Continuing on my previous post:
The 42 tilings here also represent the Catalan number C7. Surely there is a meaningful / easily describable bijection from these tilings to the heptagon triangle dissections [see previous post]. Help me find it?
