The contact bridge in the original sampled group frame

  1. theorem OAI.PolycyclicRecognition.sampled_coneProbe_dist line 15

    Source documentation

    Translate both probes by the same sampled root element.

  2. theorem OAI.PolycyclicRecognition.exists_sampled_contact_pivot_bridge line 35

    Source documentation

    The metric bridge joins the actual first and second probes after the same root translation used in the source count. The normalized inside letter is the inverse image of the original neighboring step.
