Presentation

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

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

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