Presentation

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

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

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