complete description is provided for the unitary normalizer of the diagonal Cartan subalgebra D2 in the 2-adic ring C*-algebra Q2, which generalizes and unifies analogous results for Cuntz and Bunce-Deddens algebras. Furthermore, the inclusion O2 \subset Q2 is proved not to be regular. Finally, countably many novel permutative endomorphisms of Q2 are exhibited with prescribed
images of the generator U.
