We find new relations in the mapping class group of a genus 2 surface with n boundary components for n = 1,..., 8 that induce a genus 2 Lefschetz fibration CP2 # 13 CP2 → S2 with n disjoint sections. As a consequence, we show any holomorphic genus 2 Lefschetz fibration without separating singular fibers admits a section. © 2010 by Pacific Journal of Mathematics.
