Presentation

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

A minimal faithful permutation representation — 3 generators on 28 points:

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