Exponential generating function

Summary

An exponential generating function encodes a sequence (an)(a_n) as the series ∑anxn/n!\sum a_n x^n / n!. It is the natural tool to count labelled structures, because products give binomial convolutions. The node exponential generating function gives the precise definition.

What this node needs for W1
  • an inventory row: the row of the inventory that the node accounts for (0 of 1)

The writing levels say how complete the text of a node is. They do not measure its truth.
