Presentation

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

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

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