Let $M$ be a compact Riemannian symmetric space. By the classification of Cartan, it belongs to the table of homogeneous spaces given in the Wikipedia page:
In the Berger classifiction of holonomy groups
the symmetric case is omitted because
the holonomy group can easily be read off the Cartan classification in the symmetric space case.
How does this "reading off" work exactly. Can someone point to me a list of the holonomy groups of the compact symmetric spaces?
