Presentation

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

A minimal faithful permutation representation — 3 generators on 32 points:

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