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