[seqfan] additions for completeness' sake

[Wouter Meeussen]

A001700         C(2n+1, n+1): number of ways to put n+1 indistinguishable 
balls into 2n+1 distinguishable boxes = number of (n+1)-st degree monomials 
in n+1 variables = number of monotone maps from 1..n+1 to 1..n+1.

This (Offset 0) sequence thus also counts the monomial symmetric functions 
of (degree=number of variables).
Now, the monomial symmetric functions are only one of a set of 5, the others 
are

Power Sum Symmetric Polynomials, Complete Homogeneous Symmetric Polynomials, 
Elementary Symmetric Polynomials and Schur Polynomials:

So I looked them up, and it turns out only the Power Sum Symm. poly's give a 
hit in OEIS:
1, 6, 39, 356, 4055, 57786, 983535, 19520264, 441967518
A124577:  "Define p(alpha) to be the number of H-conjugacy classes where H 
is a Young subgroup of type alpha of the symmetric group S_n. Then a(n) = 
sum p(alpha) where |alpha| = n and alpha has at most n parts."
without ('direct') mention of symmetric functions.

no hits for the others:
Complete Homogeneous Symmetric Polynomials
1, 7, 55, 631, 8001, 130453, 2323483, 48916087, 1129559068

Elementary Symmetric Polynomials
1, 5, 37, 405, 5251, 84893, 1556535, 33175957, 785671039

Schur Polynomials
1, 4, 19, 116, 751, 5552, 43219, 366088, 3245311
though this one is 'hidden' as main diagonal of triangle A191714.

This suggests looking at these symmetric poly's as triangular tables like 
A191714,
with separate entries for their main diagonals and for their row sums.

Would this be too much ballast?
Would anyone ever look them up?
