Abstract
We classify the extreme and exposed symmetric bilinear forms of the unit ball of the space of symmetric bilinear forms on ℝ2 with hexagonal norms. We also show that every extreme symmetric bilinear forms of the unit ball of the space of symmetric bilinear forms on ℝ2 with hexagonal norms is exposed.
