Presentation

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

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

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