A directed tree is a rooted tree if there is one vertex (the root) of in-degree 0 and every other vertex has in-degree 1. The depth of a rooted tree is the length of a longest path from the root. A directed graph G is called n-unavoidable if every tournament of order n contains it as a subgraph. M.

## Abstract We show that each partial order ≤ of height 2 can be represented by spheres in Euclidean space, where inclusion represents ≤. If each element has at most __k__ elements under it, we can do this in 2__k__ − 1‐dimensional space. This extends a result (and a method) of Scheinerman for the
## Abstract A __k__‐graph, __H__ = (__V, E__), is __tight__ if for every surjective mapping __f__: __V__ → {1,….k} there exists an edge α ϵ __E__ sicj tjat __f__|~α~ is injective. Clearly, 2‐graphs are tight if and only if they are connected. Bounds for the minimum number ϕ of edges in a tight __k_
