Presentation

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

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

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