Query: Coincident Rigidity of 2-Dimensional Frameworks   Fekete, Jord\'an and Kaszanitzky [4] characterised the graphs which can be
realised as 2-dimensional, infinitesimally rigid, bar-joint frameworks in which
two given vertices are coincident. We formulate a conjecture which would extend
their characterisation to an arbitrary set T of vertices and verify our
conjecture when |T| = 3.
