Triple

Given a phrase, classify it is english named entity (e.g., persons, organizations, works of art) in Latin script, or not (e.g., literals, dates, URLs, verbose phrases). For disambiguation, the statement where the phrase occurs as object is also given. Please return a JSON object with `phrase` (string, the phrase being analyzed) and `is_ne` (boolean, indicating whether the phrase is a Named Entity).

Phrase: Steiner chain | Statement: [Jakob Steiner, notableWork, Steiner chain]

Target entity: Steiner chain
Context triple: [Jakob Steiner, notableWork, Steiner chain]

• A. Tusi couple
  The Tusi couple is a geometric device from medieval Islamic astronomy that generates linear motion from the sum of two circular motions, later influencing Copernican models of planetary motion.
• B. Soddy circle
  A Soddy circle is one of the circles in a configuration of four mutually tangent circles, central to the geometric problem described by Descartes' circle theorem.
• C. Poncelet polygon
  A Poncelet polygon is a cyclic polygon that can be simultaneously inscribed in one conic and circumscribed about another, illustrating Poncelet’s porism in projective geometry.
• D. Miquel circle
  The Miquel circle is a notable circle in geometry that passes through the three points where the circumcircles of the triangles formed by choosing three vertices of a quadrilateral intersect.
• E. Rowland circle geometry
  Rowland circle geometry is an optical configuration used in spectrometers where a concave diffraction grating and its focal curve lie on a common circle to achieve high-resolution wavelength dispersion.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Generate a one-sentence description of the target entity. 
You are given a context triple in the form (subject, predicate, object), where the object is the target entity. 
# Instructions
Use the triple to infer relevant information about the entity. Describe the entity based on what is most defining, well-known. 
Avoid repeating the information from the triple, unless really essential.
# Response Format
Return only the sentence: "Description: [one-sentence description of the target entity]"

Entity: Steiner chain
Triple: [Jakob Steiner, notableWork, Steiner chain]

Steiner chain is a configuration in geometry consisting of a sequence of circles each tangent to two given non-intersecting circles and to its neighboring circles in the chain.
