Presentation

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

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

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