Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 256

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

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