Presentation

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

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

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