Presentation

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

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

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