Summary

The elementary symmetric polynomials in $n$ variables are the sums of all products of $k$ distinct variables, for $k = 0, \dots, n$ . They generate all symmetric polynomials. The definition of the elementary symmetric polynomials gives the formula.

What this node needs for W2

edge instance_of in: at least two examples (0 of 2)
edge not_instance_of in: at least one non-example (0 of 1)
edge specializes both: the more general notions and the special cases (0 of 1)

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