Presentation

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

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

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