%N A triangle related to the a(n) formulas for the rows of the ED2 array A167560.
%C The a(n) formulas given below correspond to the first ten rows of the ED2 array A167560.
%C The recurrence relations for the a(n) formulas for the left hand triangle columns, see the cross-references below, lead to the sequences A003148 and A007318.
%e Row 1: a(n) = 1.
%e Row 2: a(n) = 2*n + 0.
%e Row 3: a(n) = 3*n^2 + 1*n + 2.
%e Row 4: a(n) = 4*n^3 + 4*n^2 + 16*n + 0.
%e Row 5: a(n) = 5*n^4 + 10*n^3 + 67*n^2 + 14*n + 24.
%e Row 6: a(n) = 6*n^5 + 20*n^4 + 202*n^3 + 124*n^2 + 368*n + 0.
%e Row 7: a(n) = 7*n^6 + 35*n^5 + 497*n^4 + 601*n^3 + 2736*n^2 + 444*n + 720.
%e Row 8: a(n) = 8*n^7 + 56*n^6 + 1064*n^5 + 2120*n^4 + 13712*n^3 + 6464*n^2 + 16896*n + 0.
%e Row 9: a(n) = 9*n^8 + 84*n^7 + 2058*n^6 + 6096*n^5 + 53121*n^4 + 48876*n^3 + 186732*n^2 + 25584*n + 40320.

%Y A167560 is the ED2 array.
%Y A000012, A005843 (n=>1), 2*A104249 (n=>1), A167561, A167562 and A167563 equal the first sixth rows of the array.
%Y A005359 equals the first right hand triangle column.
%Y A000027, A000292, A167566, A167567 and A168304 equal the first five left hand triangle columns.
%Y A000142 equals the row sums.
%Y Cf. A003148 and A007318.
