  We study anisotropic inflation with Gauss-Bonnet correction in presence of a
massless vector field. In this scenario, exact anisotropic power-law inflation
is realized when the inflaton potential, gauge coupling function and the
Gauss-Bonnet coupling are exponential functions. We show that anisotropy
becomes proportional to two slow-roll parameters of the theory and hence gets
enhanced in presence of quadratic curvature corrections. The stability analysis
reveals that anisotropic power-law solutions remain stable over a substantially
large parameter region.
