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