Presentation

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

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

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