An element of finitely generated free lattices is called symmetricif it is fixed by all automorphisms of the lattice. We examine the lattice formedby these elements. It is known to be nonfinitely generated, and containing a sublatticeisomorphic to any finitely generated free lattice. We show that it is alsoweakly atomic, and prove two further statements regarding the doubly prime elementsof this lattice.
