Presentation

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

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

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