Presentation

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

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

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