# Subgraphs II

Number of Nodes:
Connect Node $$i$$ to Node $$i$$ + mod $$n$$

Highlight edge:

The subgraphs generated by this applet are created using a particular pattern. The lengths $$l$$ of the edges in the graph are fixed. The $$i$$th node is connected to node $$(l+i)$$ mod $$n$$, where $$n$$ is the number of nodes. The result is a regular star polygon, unless $$l = 0$$ mod $$n$$ or $$n$$ is even and $$l = n/2$$.
