摘要：
We determine the combinatorial and the ordinary depth of the maximal subgroups of the simple Ree groups (2)G(2)(q). As an application of these calculations, we determine the subdegrees of primitive actions of the groups (2)G(2)(q). We also improve an earlier estimate of Burness, Liebeck, and Shalev on the base size of" non-standard" primitive actions of (2)G(2)(q) on the coset space of maximal subgroups from 3 to 2.
