%N Irregular triangle read by rows, giving coefficients of polynomials arising as numerators of certain Hilbert series.
%C The row 1,8,22,8,1 occurs on p. 78 of Ottaviani as the numerator for the Hilbert series of the invariant ring of eight ordered points in a projective space. - _Tom Copeland_, Feb 27 2020
