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