Presentation

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

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

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