- theorem
OAI.PolycyclicRecognition.exists_sampled_contact_pivot_bridgeline 35Source 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.
