Presentation

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

A minimal faithful permutation representation — 5 generators on 28 points:

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