Actual tiled probes in the three Cartan template boxes

  1. structure OAI.PolycyclicRecognition.CartanWordModel.TiledProbeBoxData line 29

    Source documentation

    Fixed source box data; packaging it keeps later three-chain applications small when the ambient algebra is an actual tangent Lie algebra.

    Source documentation

    The ideal-section sampler and both reverse-flow samplers lie in the three actual ambient word boxes. Their bases and the first radius are chosen uniformly before the scale, partition and flow.
