Presentation

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

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

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