Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 512

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

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