Presentation

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

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

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