Abstract
We classify, up to equivalence, the orientation-reversing finite non-abelian actions
on RP3 which respect a genus 1 Heegaard decomposition. A description is given
for each action along with its quotient type. There are seven different quotient types, and for each
quotient type there is only one equivalence class. Examples are given of non-abelian actions
which do not respect a genus 1 Heegaard decomposition.
