Presentation

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

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

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