Presentation

minimal degree	μ(G) = 32
transitive degree	μ_t(G) = 128

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

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