Presentation

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

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

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