Presentation

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

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

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