Presentation

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

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

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