Done.
]]>Thanks for asking! That is my own preference, yes.
]]>Excellent, thanks! These additional properties you mention seem to advocate the notation which you used for the falling factorial at binomial theorem – would you prefer to use that as the main notation in this article as well?
]]>I added some more material (some of which was also at binomial theorem), mainly about the context of finite difference calculus.
]]>I created a stub for falling factorial, mainly to record the simple fact I learned yesterday that it counts the number of injections between two finite sets.
