Presentation

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

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

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

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