In the mathematical field of graph theory, the double-star snark is a snark with 30 vertices and 45 edges.

As a snark, the double-star graph is a connected, bridgeless cubic graph with chromatic index equal to 4.

The double-star snark is non-planar and non-hamiltonian but is hypohamiltonian.

[3] It has book thickness 3 and queue number 2.
