Query: Flocks of Cones: Star Flocks   The concept of a flock of a quadratic cone is generalized to arbitrary cones.
Flocks whose planes contain a common point are called star flocks. Star flocks
can be described in terms of their coordinate functions. If the cone is "big
enough", the star flocks it admits can be classified by means of a connection
with minimal blocking sets of Redei type. This connection can also be used to
obtain examples of bilinear flocks of non-quadratic cones.
