A number of communication stations equipped for communicating with each other, often on a definite time schedule and in a definite sequence.

1. Threads or cords tied together at regular intervals to form a mesh.

2. A series of surveying or leveling stations that have been interconnected in such a manner that closed loops or circuits have been formed, or that are arranged so as to provide a check on the consistency of the measured values. Also known as network.

1. In structural petrology, coordinate network of meridians and parallels, projected from a sphere at intervals of 2°; used to plot points whose spherical coordinates are known and to study the distribution and orientation of planes and points. Also known as projection net; stereographic net.

2. A form of horizontal patterned ground whose mesh is intermediate between a circle and a polygon.

1. A set whose members are indexed by elements from a directed set; this is a generalization of a sequence.

2. A nondegenerate partial plane satisfying the parallel axiom.

Any fabric made in open hexagonal mesh.
