Presentation

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

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

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