Presentation

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

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

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