Presentation

minimal degree	μ(G) = 32
transitive degree	μ_t(G) = 128

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

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