Abstract: We consider the fixed point subalgebras of higher-dimensional rational non-commutative tori induced by finite order automorphisms derived from a diagonal extension of the canonical ${SL(2,{\mathbb Z} )} $ action on rotation algebras. We give an alternative characterization and determine their $K$-theory.
