Presentation

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

A minimal faithful permutation representation — 6 generators on 32 points:

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