Presentation

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

A minimal faithful permutation representation — 4 generators on 28 points:

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