Presentation

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

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

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