%N Second of four sequences representing the lexicographical minimal decomposition of n in 4 squares: n = A064873(n)^2 + a(n)^2 + A064875(n)^2 + A064876(n)^2.
%e a(19) = 1: 19 = A064873(19)^2 + a(19)^2 + A064875(19)^2 + A064876(19)^2 = 0 + 1 + 9 + 9 and the other decomposition (1, 1, 1, 4) is greater than (0, 1, 3, 3).
%Y Cf. A064873, A064875, A064876, A064877.
