Presentation

minimal degree	μ(G) = 32
transitive degree	μ_t(G) = 64

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

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