Summary
| Description |
English: 13 plane trees with four ordered leaves, with all root-leaf paths the same length and with different numbers of nodes at each level. The gaps between leaves are labeled by the height above the leaves of the lowest common ancestor of the two adjacent leaves; these heights induce a weak ordering of the gaps. As shown by Arthur Cayley in 1859, the trees of this type are counted by the ordered Bell numbers. |
