Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 128

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

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