  A method is presented to search for a hypertorus symmetry axis by the
alignment of distant objects. This offers greater sensitivity than previously
proposed object-based methods that rely on accurate true distances. When
applied to the catalog of objects with z > 1, we find no evidence for a compact
dimension. We deduce a lower limit to the compact dimension size D > 0.9 of the
distance to the cosmic horizon. This is consistent with independent constraints
from the recent analysis of the WMAP microwave background data.
