Presentation

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

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

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