Presentation

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

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

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