Presentation

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

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

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