Presentation

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

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

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