%N Numbers of terms in expressions for coefficients of Euler-Lagrange tensors in terms of Riemann-Christoffel curvature tensor and two of its contractions (viz., the Ricci curvature tensor and the Riemann curvature scalar) for n-dimensional differentiable manifolds having a general linear connection.
%C The six known terms of this sequence coincide with the first six terms of A167551. - _Johannes W. Meijer_, Nov 12 2009
