In the mathematical field of graph theory, the Szekeres snark is a snark with 50 vertices and 75 edges. It was the fifth known snark, discovered by George Szekeres in 1973.
As a snark, the Szekeres graph is a connected, bridgeless cubic graph with chromatic index equal to 4. The Szekeres snark is non-planar and non-hamiltonian but is hypohamiltonian.
Another well known snark on 50 vertices is the Watkins snark discovered by John J. Watkins in 1989.

Famous quotes containing the word snark:
“But oh, beamish nephew, beware of the day,
If your Snark be a Boojum! for then
You will softly and suddenly vanish away,
And never be met with again!”
—Lewis Carroll [Charles Lutwidge Dodgson] (1832–1898)
