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