Subdivisions of a graph
Let $G$ and $H$ be two given graphs. Suppose $H$ is smaller than $G$.
How do I check whether $G$ contains a subgraph which is an even (or odd) subdivision of $H$?
I know that the command: G.minor(H) will tell whether $G$ contains a subgraph which is a subdivision of $H$.
But I'm looking for whether it contains an even subdivision. How do I do this?
