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