Chest agrees:
dep          #nodes     quot        sum nodes
  0               1 [  0.000]               1
  1              47 [ 47.000]              48

Yes:
dep          #nodes     quot        sum nodes
  0               1 [  0.000]               1
  1              22 [ 22.000]              23

  3           12571 [ 25.603]           13085
  4          295376 [ 23.497]          308461
  5         8296614 [ 28.088]         8605075

Again, Chest agrees with Sinan:
dep          #nodes     quot        sum nodes
  0               1 [  0.000]               1
  1              37 [ 37.000]              38
  2            1492 [ 40.324]            1530
  3           48572 [ 32.555]           50102
  4         2010006 [ 41.382]         2060108
  5        67867493 [ 33.765]        69927601
