Presentation

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

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

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