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