Presentation

minimal degree	μ(G) = 32
transitive degree	μ_t(G) = 128

A minimal faithful permutation representation — 7 generators on 32 points:

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

GAP

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