Presentation

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

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

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