French Silurian coral to be identified

[aldo66]

Hello,
I recently found a coral ball (I suppose...) in a Silurian level in the South of France.
I sawed it, sanded it and polished it and here is the result!
The size is about 7 centimeters
Is it possible to identify it more precisely?
I appeal to your knowledge
Thanks in advance

given subspherical to ( sub )pentagonal/ polygonal corallites * ,a favositid affinity might be postulated

* for the nonce, i will call them that, because the OP calls his piece a "coral" ....

I agree it is a favositid, and think it is probably Favosites itself.
