Presentation

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

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

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