Presentation

minimal degree	μ(G) = 32
transitive degree	μ_t(G) = 128

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

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