Presentation

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

A minimal faithful permutation representation — 4 generators on 28 points:

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