Presentation

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

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

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