Presentation

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

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

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