Presentation

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

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

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