Presentation

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

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

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