Presentation

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

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

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