Presentation

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

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

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