Bolza surface
In mathematics, the Bolza surface, alternatively, complex algebraic Bolza curve (introduced by Oskar Bolza (1887)), is a compact Riemann surface of genus 2 {\displaystyle 2} with the highest possible order of the conformal automorphism group in this genus, namely G L 2 ( 3 ) {\displaystyle GL_{2}(3)} of order 48 (the general linear group of 2 × 2 {\displaystyle 2\times 2} matrices over the finite field F 3 {\displaystyle \mathbb {F} _{3}} ). Its full automorphism group (including reflections) is a semi-direct product G L 2 ( 3 ) ⋊ Z 2 {\displaystyle GL_{2}(3)\rtimes \mathbb {Z} _{2}} of order 96.
