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