Although questions about Eulerian circuits, paths, and covering edges by edge disjoint paths are easily answered for graphs or directed graphs, they are not easily answered if some edges are directed and others are not. We give necessary and sufficient conditions for an Eulerian path or circuit, and
Consider the subset graph G(n, k) whose vertex set C(n, k) is the set of all n-tuples of 'O's' and 'l's' with exactly k 'I's'. Let an edge exist between two vertices a and b in G(n,k) if and only if a can be transformed into b by the interchange of two adjacent coordinate values, with the first and
