Presentation

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

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

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