Presentation

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

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

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