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