Presentation

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

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

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