Presentation

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

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

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