Presentation

minimal degree	μ(G) = 32
transitive degree	μ_t(G) = 128

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

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