Presentation

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

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

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