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