Presentation

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

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

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