Presentation

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

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

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