Presentation

minimal degree	μ(G) = 32
transitive degree	μ_t(G) = 256

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

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