Presentation

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

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

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