Guys, could anyone tell me what is an invert transform by definition, I simply cannot find any source about it. It is one kind of the transform that preserves the hankel transform; the other one is Binomial transform. Thanks!

Oh, I am sorry that I have spamed.. but I have figured out the answer... from Online Encylopedia of Integer Sequence website.. it is $$b_n=1/(1+\sum_i^na_ix^i)$$, pretty cool...
