Presentation

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

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

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