Presentation

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

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

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