Presentation

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

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

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