Presentation

minimal degree	μ(G) = 32
transitive degree	μ_t(G) = 256

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

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