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