Presentation

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

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

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