Presentation

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

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

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