Abstract: A compact (orientable or non-orientable) surface of genus $ g$ is said to be extremal if it contains an extremal disc, that is, a disc of the largest radius determined only by $ g$. The present paper concerns non-orientable extremal surfaces of genus $ 5$. We represent the surfaces as side-pairing patterns of a hyperbolic regular $ 24$-gon, that is, a generic fundamental region of an NEC group uniformizing each of the surfaces. We also describe the group of automorphisms of the surfaces with a unique extremal disc.
