Presentation

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

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

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