Presentation

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

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

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