 OFFSET 1,1 COMMENTS First 8 such quadruples are: {{3362, 482, 359, 2}, {3473, 1288, 1016, 8}, {4194, 1282, 567, 162},{4743, 2482, 882, 18}, {5024, 2720, 1376, 305},{5378, 2018, 1346, 98}, {5378, 1346, 863, 98},{5522, 4082, 3314, 407}. LINKS EXAMPLE First quadruple is {3362, 482, 359, 2}. Six pairwise sums are all squares: 3362 + 482 = 62^2, 3362 + 359 = 61^2, 3362 + 2 = 58^2, 482 + 359 = 29^2, 482 + 2 = 22^2, 359 + 2 = 19^2.
