Presentation

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

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

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