Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 256

A minimal faithful permutation representation — 3 generators on 28 points:

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