Presentation

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

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

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