Presentation

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

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

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