SUMMARY: (...): Compact non-orientable surfaces of genus 6 with extremal me
 tric discs
DESCRIPTION:: A compact hyperbolic surface of genus g is said to be extrema
 l if it admits an extremal disc\, a disc of the largest radius determined 
 by g\, where genus g is the number of handles if S is orientable or the nu
 mber of cross caps if S is non-orientable. In this talk we shall consider 
 how many extremal discs are embedded in a compact non-orientable surface o
 f genus 6. We know the answer for the surfaces of g=3\, 4\, 5 and also g>6
 \, so that g=6 is the final genus in our interest. By showing side-pairing
  patterns of the regular 30-gon\, we present all non-orientable extremal s
 urfaces of genus 6 admitting more than one extremal disc. We also determin
 e the group of automorphisms for these surfaces.
