（各向同性）正交图O（2ν+δ,q）在奇数特征的Fqof上，其中引入了ν大于或等于1和δ=0,1或2。当ν=1时，O（2·1+δ,q）是完全图。当ν大于或等于2时，O（2ν+δ,q）是强规则的，计算它的参数，以及它的色数。确定了正交图的自同构群。
The (isotropic) orthogonal graph O(2ν+δ,q) over Fqof odd characteristic, where ν⩾1 and δ=0,1 or 2 is introduced. When ν=1, O(2⋅1+δ,q) is a complete graph. When ν⩾2, O(2ν+δ,q) is strongly regular and its parameters are computed, as well as its chromatic number. The automorphism groups of orthogonal graphs are also determined.
