Presentation

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

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

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