Section/integration points for beam elements in ABAQUS

Question

I'd like to work with beam elements in ABAQUS. I don't quite understand what is meant by integration points and section points. For a rectangular beam, it says that there are 25 section points for section integration. On the other hand, as I understand it, a B31 beam element has 1 integration point, a B32 has 2 and a B33 has 3. I therefore assume that these 1, 2 or 3 points are the Gauss points for integrating the stiffness matrix, and these points are on the axis of the beam. That's I don't understand what the 25 section points are for.

Can someone help ?

Thanks

I tried to display the stresses and strains as a function of the section point, but I didn't get any dependencies.
