Talk:Touchard polynomials

From Wikipedia, the free encyclopedia

[edit] Bell polynomials

I just noticed that exponential polynomials redirects to Touchard polynomials, but exponential polynomial redirects to Bell polynomials. From what I can tellm the two are closely related, but the relationship is not really spelled out. Can someone who knows more a) make the redirect unambiguous (and as specific as possible) and b) take whatever other measures are useful? Should the articles possibly be merged?
