Presentation

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

A minimal faithful permutation representation — 6 generators on 32 points:

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