Presentation

minimal degreeμ(G) = 32
transitive degreeμt(G) = 256

A minimal faithful permutation representation — 5 generators on 32 points:

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

GAP

Past the SmallGroups library coverage — no SmallGroups id. Construct it from its polycyclic presentation:
