Presentation

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

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

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