Presentation

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

A minimal faithful permutation representation — 3 generators on 32 points:

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