Presentation

minimal degree	μ(G) = 32
transitive degree	μ_t(G) = 64

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

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