Summary: Let $Gamma$ be a distance-regular graph of diameter $d$ and valency $k > 2$. Suppose there exists an integer $s$ with $dle2s$ such that $c _{ i } = b _{ d-i }$ for all 1 $leiles$. Then $Gamma$ is an antipodal double cover.
Keywords: distance-regular graph, antipodal double cover, box, brox
