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