Presentation

minimal degree	μ(G) = 32
transitive degree	μ_t(G) = 64

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

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