Do f-orbitals form sigma bonds?

[Saitama]

Homework Statement

This is not a homework question.
I found a question in my book that which orbitals form sigma bonds.
I am wondering if any of the f-orbitals form sigma bonds?

I don't know, but I strongly doubt.

This will be handwavy.

For sigma bond you need orbitals of a correct symmetry. Assuming there exists an f orbital of a correct symmetry (intuition tells me it does) it should be able to create sigma orbital. But f orbitals are "deep" in the atom and they don't participate in bonding.

I think you are right.
After a deep search too, i wasn't able to find any information on f-orbital sigma bonds.
But what i found is that they form delta bonds.
