Presentation

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

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

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