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