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