 A064875 Third of four sequences representing the lexicographical minimal decomposition of n in four squares: n = A064873(n)^2 + A064874(n)^2 + a(n)^2 + A064876(n)^2. 4
 0, 0, 1, 1, 0, 1, 1, 1, 2, 0, 1, 1, 2, 2, 2, 2, 0, 1, 3, 3, 2, 2, 3, 3, 2, 0, 1, 1, 1, 2, 2, 2, 4, 4, 3, 3, 0, 1, 1, 1, 2, 4, 4, 3, 2, 3, 3, 3, 4, 0, 1, 1, 4, 2, 2, 2, 4, 2, 3, 3, 3, 5, 5, 5, 0, 1, 1, 3, 2, 2, 5, 5, 6, 3, 5, 5, 6, 3, 5, 5, 4, 0, 1, 1, 4, 2, 2, 2, 6, 5, 3, 3, 3, 5, 3, 3, 4, 4, 7, 7, 0, 1, 1, 1, 2 (list; graph; refs; listen; history; text; internal format)
 OFFSET 0,9 LINKS EXAMPLE a(19) = 3: 19 = A064873(19)^2 + A064874(19)^2 + a(19)^2 + A064876(19)^2 = 0 + 1 + 9 + 9 and the other decomposition (1, 1, 1, 4) is greater than (0, 1, 3, 3). CROSSREFS Cf. A064873, A064874, A064876, A064877.
