%N Triangle of coefficients for the Shift-Moebius transform, read by rows.
%C Column k = Shift-Moebius transform of a sequence of all zeros except for a single '1' in position k: [0,0,0,..(k-1)zeros..,1,0,0,0,...].
%C Column 1 is A117166, the Shift-Moebius transform of [1,0,0,0,...].
%C Column 2 is A117167, the Shift-Moebius transform of [0,1,0,0,...].
%C Column 3 is A117168, the Shift-Moebius transform of [0,0,1,0,...].
%C Row sums give A117169, the Shift-Moebius transform of [1,1,1,...].
%F The Shift-Moebius transform of a sequence B is equal to the limit of the iteration: let C_1 = B and for k>1, C_{k+1} = Moebius transform of C_k preceded by k zeros, then shift left k places (to drop the leading k zeros).
%F Triangle A117162 is a good example, starting with A008683 in column 1 as C_1 and each column k, C_k, is obtained using the above iteration, so that the columns converge to A117166.
