Presentation

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

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

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