Presentation

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

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

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