Presentation

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

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

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