Presentation

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

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

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