Hexagon has no degrees of freedom but can seen as directed edges. Hexagons of symmetry g2, i4, and r12, as parallelogons can tessellate the Euclidean plane by translation. Other hexagon shapes can tile the plane with different orientations. The 6 roots of the simple Lie group , represented by a Dynkin diagram , are in a regular hexagonal pattern. The two simple roots have a 120° angle between them. The 12 roots of the Exceptional Lie group G2, represented by a Dynkin diagram are also in a hexagonal pattern. The two simple roots of two lengths have a 150° angle between
Snakes on a Plane landing, the plane makes it to the terminal. The passengers leave the plane and antivenom is given to those who need it. Just as Flynn and Sean are about to disembark the plane, a final snake jumps out and bites Sean in the chest. Flynn draws his gun and shoots the snake, and paramedics rush to Sean, who is unharmed due to his wearing a ballistic vest. As a token of gratitude, Sean later takes Flynn to Bali and teaches him how to surf.
