Presentation

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

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

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