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