Presentation

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

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

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