Presentation

minimal degree	μ(G) = 32
transitive degree	μ_t(G) = 64

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

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