Presentation

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

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

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