Presentation

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

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

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