%N Triangle, read by rows, such that diagonal n is equal to the Euler transform of row n, where each row starts with 1.

%C Row sums are A093629. Central terms in even rows form A093630.

%e The Euler transform of row 4: [1,4,4,3,1], equals diagonal 4: [1,5,9,22,39,81, 137,...]; the main diagonal has an index of zero.
