[seqfan] new array with polynomial coefficients A197184

[Richard Mathar]

I have stumbled across an array of polynomial coefficients

                                       1

                                    -1 + x

                                            2
                                  -1 - x + x

                                          2    3
                               7 - 2 x - x  + x

                                          2    3    4
                          -13 + 12 x - 3 x  - x  + x

                      -17 - 22 x + 18 x  - 4 x  - x  + x

For those who like Stirling and Bernoulli-related arrays, it may be some
sort of challenge to figure out what the recurrences, generating functions
etc might be. Apparently one gets polynomial recurrences down each column
if the rows are reversed, i.e., if the polynomial coefficients are listed
along declining exponents.
