Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 64

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

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