Presentation

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

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

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