8427, 2933, x, 2689, 9305, L, 9263, 2671

['t', 845, 'T', '5285', '7837', 'N', 6717], [7211, 7903, 'U', 'T', '5285', '7837', 'D', 'U', 'R']
T, 5285, 7837

[8325, 'J', '1099', 'p', 's', '4837', '9163', '7431', '9555', 'O', 'x', 4625, 2525], ['d', 'C', '1099', 'p', 's', '4837', '9163', '7431', '9555', 't', 'O', 8579, 'K', 6715]
