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

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

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