Presentation

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

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

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