%N A107102 Matrix inverse of A100862.
%C A107102 Column 0 is signed A001515 (Bessel polynomial). Column 1 is A107103. Row sums are zeros for n>0. Absolute row sums form A107104, which equals 2*A043301(n-1) for n>0.
%C A107102 The row polynomials p_n(x) of this entry are (-1)^n B_n(1-x), where B_n(x) are the  modified Carlitz-Bessel polynomials of A001497, e,g, (-1)^2 B_2(1-x) = (1-x) + (1-x)^2 = 2 - 3 x + x^2 = p_2(x). - _Tom Copeland_, Oct 10 2016
