Description
The biclique partition number of a graph.
The biclique partition number of a graph is the minimum number of pairwise edge disjoint complete bipartite subgraphs so that each edge belongs to exactly one of them. A theorem of Graham and Pollak [1] asserts that the complete graph $K_n$ has biclique partition number $n - 1$.

Description
The shape of the tree associated to a permutation.
A permutation can be mapped to a rooted tree with vertices {0,1,2,â€¦,n} and root 0 in the following way. Entries of the permutations are inserted one after the other, each child is larger than its parent and the children are in strict order from left to right. Details of the construction are found in [1].
The statistic is given by $2^w 3^h$, where $w$ is the width St000325The width of the tree associated to a permutation. and $h$ is the height St000308The height of the tree associated to a permutation. of this tree.

The shape of the tree associated to a permutation.

A permutation can be mapped to a rooted tree
as described on the [[http://www.findstat.org/Permutations#Other_maps|permutations page]], and twith vertices {0,1,2,â€¦,n} and root 0 in the following way. Entries of the permutations are inserted one after the other, each child is larger than its parent and the children are in strict order from left to right. Details of the construction are found in [1].
T
he statistic is given by 2^w 3^h, where w is the width [[St000325]] and h is the height [[St000308]] of this tree.
