Presentation

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

A minimal faithful permutation representation — 3 generators on 32 points:

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