Presentation

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

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

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