Presentation

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

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

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