Hi, I'm on Maple 2020 on Mac, and running this:

Captura-de-Pantalla-2020-05-16-a-la-s-23-14-57" />

In fact, that isn't the Chromatic number of that graph. Is not possible to color that graph with 2 colors becuase C7 (Cycle with 7 vertex) is a subgraph which is imposible to color with 2 colors. Am I doing something wrong? Can you replicate this? Is this a bug or is me?

Thanks
