Presentation

minimal degree	μ(G) = 32
transitive degree	μ_t(G) = 64

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

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