Presentation

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

A minimal faithful permutation representation — 3 generators on 32 points:

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