Presentation

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

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

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