Presentation

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

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

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