Presentation

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

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

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