Presentation

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

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

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