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