Presentation

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

A minimal faithful permutation representation — 6 generators on 28 points:

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