Presentation

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

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

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