Presentation

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

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

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