Presentation

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

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

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