Presentation

minimal degreeμ(G) = 32
transitive degreeμt(G) = 128

A minimal faithful permutation representation — 4 generators on 32 points:

(9,10)(11,15,16,13)(12,14)(17,18,21,26,22,24,20,25)(19,27,29,31,28,32,30,23);(1,2,3,5,4,6,7,8)(9,11)(10,13)(12,16)(14,15)(17,19)(18,23,24,31)(20,29)(21,30)(22,28)(25,27,26,32);(11,16)(13,15);(19,28)(23,31)(27,32)(29,30)

Polycyclic presentation:

2^10|a^2=g,b^2=e,e^2=h,f^2=j,g^2=j,b^a=bf,c^b=ci,d^b=dj,e^a=ej,f^a=fi,g^b=gij
