Presentation

minimal degree	μ(G) = 32
transitive degree	μ_t(G) = 64

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

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