Presentation

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

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

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