Presentation

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

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

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