%N Eigentriangle by rows, T(n,k) = A010060(n-k+1)*A144026(k-1), 1 <= k <= n.

%C Left column = the Thue-Morse sequence A010060 starting with offset 1.

%C Right border = A144026: (1, 1, 2, 3, 6, 10, 18, ...).

%C Row sums = A144026: (1, 2, 3, 6, 10, 18, ...).

%C Sum of n-th row terms = rightmost term of next row.

%F Eigentriangle by rows, T(n,k) = A010060(n-k+1)*A144026(k-1), 1 <= k <= n.

%F The triangle is generated from the Thue-Morse sequence A010060 using offset 1:

%F (1, 1, 0, 1, 0, 0, 1, ...). A144026 is (1, 1, 2, 3, 6, 10, 18, ...).

%e Row 4 = (1, 0, 2, 3) = termwise products of (1, 0, 1, 1) and (1, 1, 2, 3), where (1, 0, 1, 1) = the first 4 terms of A010060, reversed with offset 1.

%e (1, 1, 2, 3) = first 4 terms of A144026: (1, 1, 2, 3, 6, 10, 18, ...).
