Presentation

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

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

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