Presentation

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

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

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