Presentation

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

A minimal faithful permutation representation — 4 generators on 32 points:

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