WebApr 26, 2024 · Update So I attempted to draw a graph as presented below From what I noticed A>B>F>E>A is a 4-cycle. A>D>E>A and B>C>F>B are 3-cycles. However, in the graph, A>B>C>F>E>A is a cycle of length 5 and A>B>C>F>E>D>A is a cycle of length 6. So, there are other cycles in the graph with cycle lengths are more than 3 and 4.
