Presentation

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

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

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