Presentation

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

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

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