Presentation

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

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

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