Sixnode

Sixnode is a term used across several disciplines to denote a structure composed of six nodes or elements, typically illustrating a small-scale network, cluster, or graph. The meaning is context dependent, and the term is not tied to a single standardized specification.

In graph theory, a six-node graph has six vertices. Researchers study properties such as connectivity, degree sequences, and isomorphism classes. Common six-node examples include the six-cycle C6, the complete graph K6, the bipartite graph K3,3, and the wheel graph W5, which consists of a 5-cycle plus a central hub.

In computing and networking, six-node topologies are used for small clusters, testing environments, and redundancy planning. In distributed systems, a quorum of four nodes is typically required for consensus in a six-node configuration, enabling tolerance of up to two node failures under simple majority rules. Topologies may include ring, star, mesh, or partial connectivity among the six nodes.

Outside mathematics and computing, six-node configurations appear in simplified models of biological or neural networks where six units interact at a time, or in teaching tools illustrating basic network properties.

Etymology and usage: the term sixnode combines the numeral six with node to indicate the number of elements. Because it is informal, the precise meaning of sixnode varies by field and author. See also six-node graphs and small-scale network topologies.
