Presentation

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

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

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