The algebras do not absorb the Jiang-Su algebra Z tensorially, answering a question of N. C. Phillips. They are also pairwise shape and Morita equivalent. The distinguishing invariant is the radius of comparison, a non-stable invariant of the Cuntz semigroup.12 pages, to appear in Trans. AMSOperator AlgebrasK-Theory and Homology46L35; 46L80text
