Presentation

minimal degree	μ(G) = 32
transitive degree	μ_t(G) = 128

A minimal faithful permutation representation — 4 generators on 32 points:

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