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