Presentation

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

A minimal faithful permutation representation — 5 generators on 28 points:

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