We found that a global solution can exist only when the dilaton coupling is less than a critical value which can be determined numerically. Moreover, the black hole horizon is stretched by the Gauss-Bonnet correction and the entropy is twice the value given by Bekenstein-Hawking formula.4 pages, contribution to the proceedings of the 8th Asia-Pacific International Conference on Gravitation and Astrophysics (ICGA8)High Energy Physics - TheoryExtremal dilatonic black holes in 4D Gauss-Bonnet gravitytext
